What Polyethylene is used for?

Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene.

It belongs to the alkane inert polymer, has good chemical stability, and is resistant to corrosion of acid, alkali and salt aqueous solutions at normal temperature. Because polyethylene is non-polar, it can be used as an insulating material or as a high-voltage insulating material. Under the action of the atmosphere, sunlight and oxygen, polyethylene will age, discolor, crack, it can become brittle or chalk, and lose its mechanical properties. Because polyethylene possesses these qualities and is easy to process, the degradable and recyclable research of polyethylene has far-reaching value.

Polyethylene materials are widely used for processing into films, wire, and cable sheaths, pipes, various hollow products, injection molded products, fibers, and the like. For example, a representative low-density polyethylene (LDPE), which is odorless, odorless, non-toxic, matte, milky white waxy particles, has a density of about 0.920 g/cm3, and a use temperature of -100 to 110 °C. It is insoluble in water, can withstand most of the acid and alkali erosion, has low water absorption, and can maintain softness and electrical insulation at low temperatures. Low-density polyethylene can be processed into various industrial products by processing methods such as injection molding, extrusion molding, and blow molding. It is widely used as packaging materials for various foods, clothing, medicines, fertilizers, industrial products, and agricultural films. It plays a pivotal role in the plastics industry.

We can see the presence of polyethylene in many scenarios. For example, in the industry, plastic end caps for industrial pipes, or protective plugs, flange protection caps, etc.

Food tin cans


Tinplate is a thin steel sheet coated by tin. It has an extremely beautiful metallic luster as well as excellent properties in corrosion resistance, solderability, and weldability. Tinplate is used for making all types of containers such as food cans, beverage cans, 18-liter cans, and artistic cans. Its applications are not limited to containers; recently, tinplate has also been used for making electrical machinery parts and many other products.


Tin Free Steel (TFS) is produced by applying electrolytic chromic acid treatment over steel sheets. This steel product was developed to meet economic requirements, and excels tinplate in paintability, paint adhesion and economy. It is widely used for making beverage cans and 18-liter cans. It is also used for making photographic film cases and as a protective material for optical fiber cables.


* Features of Tinplate

  • Beautiful Appearance: TIN PLATE is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.
  • Excellent Paintability & Printability: Printing is beautifully finished using various lacquers and inks.
  • Excellent Formability & Strength: By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming.
  • Excellent Corrosion Resistance:  By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents.
  • Excellent Solderability & Weldability: TIN PLATE is widely used for making various types of cans by soldering or welding.

* Features of Tin Free Steel (TFS)

  • Appearance: Even when the same surface finish as TIN PLATE is applied to the substrate steel sheet, it provides the unique surface luster characteristic of metallic chromium.
  • Corrosion resistance: As it has excellent corrosion resistance after painting, it is generally used with both surfaces painted. It can also be used with the internal surface unpainted, depending on the contents.
  • Solderability: TFS is not compatible with soldering.
  • Weldability:  Although TFS can be welded when the metallic coating layers are removed, its weldability is inferior to TIN PLATE.

Usage Precautions

  • Usage Precautions for TINPLATE: 1) As TIN PLATE is covered by soft metallic tin coatings, due precautions should be taken not to cause scratches by rough handling or vibration during transportation. 2) Paintability, printability, solderability, and mechanical properties of TIN PLATE tend to deteriorate as time elapses after production. Use as soon as possible after delivery. 3) Although TIN PLATE has excellent corrosion resistance, it tends to rust in a humid atmosphere. Use as soon as possible after unpacking. 4) Tin is dissolved by a strongly alkaline solution. When using TIN PLATE for making cans for alkaline contents, paint the internal surface. 5) As contents that contain sulfur cause blackening of the TIN PLATE surface, paint the internal surface.

  • Usage Precautions for TFS: 1) TFS is not compatible with soldering and DI forming. However, once painted, it can be used in almost all applications where TIN PLATE is used. 2) The metallic coating layer of TFS has a high electrical resistance. When welding it, the metallic coating layers in the welded areas should be removed in advance. 3) TFS tends to rust in a humid atmosphere. Use as soon as possible after unpacking. 4) The external surfaces of cans should be painted to prevent corrosion. 5) The internal surfaces should also be painted to prevent corrosion except when the content is motor oil or cooking oil. 6) TFS does not provide sacrificial protection like TIN PLATE. Due precautions should be taken not to cause scratches on the surface of TFS after it is formed into cans and painted.

plastic beach buckets

The Use Of Plastic Beach Buckets

Children love to play with sand, and it’s natural, so this plastic beach bucket should be a must for every family with children! When we were young, we took a small stick and a small bucket, and then took a small iron shovel at home to dig the sand on the street. It was a very happy time. Every time I played with the mud, I went home, then listened to my mother’s reprimand and smiled silly! Nowadays, children also like to play with sand. Nowadays, many beach toys are emerging, such as a small shovel, small shovel, small showers and so on. Moreover, the packaging is not packed in boxes as before, and these beach toys are now uniformly packed in the beach bucket. After the end of the day’s play, the children can directly put all the small pieces of small toys into the beach bucket, and then lift them up and pick them up directly. Such a packaging bucket is convenient and practical.

Plastic beach buckets

There are many other uses for plastic beach buckets, such as in the daily life, in the bathroom, it can be used as a laundry bucket, and on the balcony, it can be used as a storage bin for storing clothes.

A detailed introduction to the egg carton

An egg carton (also known as an egg box in British English) is a carton designed for carrying and transporting whole eggs.


These cartons have a dimpled form in which each dimple accommodates an individual egg and isolates that egg from eggs in adjacent dimples. This structure helps protect eggs against stresses exerted during transportation and storage by absorbing a lot of shocks and limiting the incidents of fracture to the fragile eggshells. An egg carton can be made of various materials, including foamed plastics such as polystyrene foam, clear plastic or may be manufactured from recycled paper and molded pulp by means of a mechanized paper-mâché process.


Before its invention, eggs were carried in egg baskets. A predecessor to the modern egg box was invented by Thomas Peter Bethell of Liverpool in 1906 and marketed as the Raylite Egg Box. He created frames of interlocking strips of cardboard. These frames were themselves packed in cardboard or wooden boxes for transport by road or rail.

The egg carton was invented in 1911 by newspaper editor Joseph Coyle of Smithers, British Columbia, to solve a dispute between a local farmer and hotel owner in Aldermere, near present day Telkwa, in British Columbia, over the farmer’s eggs often being delivered broken.

A version of the egg carton was patented in 1921 by Morris Koppelman.

The egg carton was patented in 1969 by United Industrial Syndicate in Maine. UIS was a division of The Portland Company. The three inventors listed on the filing are Walter H. Howarth, Gerald A. Snow, and Harold A. Doughty.

Unlike many products, trademarks and advertisements for egg brands are usually printed on the food container itself rather than on a separate container (as with breakfast cereals).[1] This single-layer, distinctive packaging distinguishes egg cartons from different producers or quality on the retail shelf.


Trays are usually used to store fresh eggs from farms or at farmers markets. Plastic egg trays are also used by egg processors to wash and sanitize eggs. A cardboard sleeve or additional trays are used to protect eggs when using a tray format.

Standard egg cartons have room for 12 eggs, but they can come in a variety of sizes, holding from 4 to 24 eggs.

stretch silicone lids

An Honest Review of Silicone stretch Lids

When we have some food left, we choose disposable products such as plastic wrap to preserve food. But this inevitably leads to waste. We are all for reducing waste. we try really hard to reduce our environmental footprint by using reusable materials whenever possible. That means we opt for microfiber cloths over paper towels, glass storage containers over zip-top baggies, and real forks and knives instead of plastic ones whenever we have takeout.

So I was pumped when those universal silicone lids started to hit the market. The premise: The seemingly simple lids sit on top of all sorts of bowls, pots, and pans, or baking dishes to create an airtight seal for cooking and storage. Because they’re made of silicone, they can go in the freezer, oven, microwave, and more. Plus, you can throw them in the dishwasher when they’re dirty. Cool! But I had some questions: Would they work with my existing kitchen stuff, would I actually use them, and are they worth buying? See? So many questions!

Using Silicone Lids in the Fridge

Theoretically, you can put one of these lids straight onto a serving bowl and then stick it in there without having to pull out a storage container. But that doesn’t make a ton of sense for us — we tend to serve our family dinners straight from the pot, and we are not going to cover those leftovers up and put them in the fridge because they’d take up way too much space. So we’d be transferring to a different container for the fridge anyway — and we may as well use one that comes with a lid.

My other complaint is that the flexible lids mean you can’t stack foods, so your leftovers couldn’t be stored super efficiently — although the same could be said about putting plastic wrap over a bowl, too. (Note: There are some versions of these that are more rigid and can be stacked, but they’re not as pretty.)

Using Silicone Lids for Cooking

For us, when it comes to stovetop cooking, we have very few pots that don’t have matching lids, and only rarely do we use a sauté pan or something where we want to trap a little extra heat but don’t have a lid. In that case, we usually find that the lid of the next size up pot will do just fine. So we don’t really need these lids for this task.

As for the oven, the ones pictured above are safe to use up to 550°F (some other brands only work up to 220°F, so be sure to check!), which means they could come in handy when baking chicken or a casserole that needs to be covered.

The spot where these things are the most useful for my family is in the microwave. Microwave cooking is where I tend to grab a paper towel to cover food, versus use a reusable item. We use the microwave at least once a day (so many dinner leftovers!), which means these could pay for themselves in paper towels alone.

Using Silicone Lids for Potlucks

If you’re someone who joins in on a lot of potlucks, these are specially useful. Because they form a seal with any material, you can use them to cover serving dishes on your way to and from a party, or to keep bugs off of food while it’s out to serve. That seems pretty handy, and they do have cute designs!

1-25L Plastic cylindrical bucket

How the 5gallon plastic bucket came to the aid of grassroots environmentalists

How the 5gallon plastic bucket came to the aid of grassroots environmentalists ?The plastic five-gallon bucket is the most humdrum of containers, yet it’s proved to be almost as versatile as duct tape. Creative sorts have turned buckets into toolboxes and ottomans, planters and panniers. And in recent years, some environmental activists have begun using the humble bucket for an even higher purpose: These days, five-gallon buckets may literally be saving lives.

Back in 1994, several years before Erin Brockovich and her boss Edward Masry saw their life stories reenacted on the big screen, Masry was representing a group of citizens from Rodeo, Calif., on the eastern side of San Francisco Bay. His clients lived near a Unocal oil refinery, and they were worried: They’d recently endured a major release of a refinery catalyst called catacarb, which had coated their neighborhoods with sticky goo. Hundreds of them had already gotten sick, and they’d been noticing odd smells around the Unocal site. “We realized there was no way for the people to monitor what was coming out of the refinery,” says Masry.

So Masry inaugurated his own monitoring program. He called up an environmental engineering firm and asked them to redesign the standard air-sampling device — known as a Summa canister, a stainless-steel unit that costs about $2,000 — into a cheap and accurate tool that private citizens could use. The engineers’ solution? The good old five-gallon bucket.

The engineers brought the cost of the sampling unit down to about $250 by housing its guts in an airtight plastic bucket. Once a “grab sample” of air is taken with the bucket, the heavy-duty Tedlar bag inside can be sealed and sent to a lab for analysis. Masry gave 30 buckets to Rodeo citizens, encouraging them to keep tabs on future releases from the Unocal refinery. “The amount of releases dropped dramatically,” he remembers. Two years later, thanks in part to the data collected by refinery neighbors, Unocal settled the citizens’ lawsuit, paying a total of $80 million to the 6,000 residents injured by the catacarb release.

Denny Larson, then part of a local group called Communities for a Better Environment, saw huge political potential in the engineers’ invention. Larson wanted an even cheaper, simpler version of the bucket, so he and his coworkers started searching for substitute parts at camping stores, boat shops, and vacuum-cleaner dealers. They eventually shaved the cost down to about $75 per unit, and designed a guerrilla environmental monitoring program that included protocols for data collection. Larson started hawking the program to grassroots activists in the Bay Area, and in 1995 his group got a private grant to take their buckets on the road. And thus the Bucket Brigade was born.

Today, there are about 25 Bucket Brigades active in the United States, ranging from California to Philadelphia and Texas to North Carolina. They keep an eye on oil refineries, chemical plants, and even large-scale hog farms. Most are based in “fenceline” neighborhoods — communities located next to industrial sites — and most use the protocols developed by Larson and his coworkers. Each has a team of “sniffers” to detect unusual odors, and a team of samplers to confirm the sniffers’ suspicions via the buckets.

Larson says he’s seen this power embraced around the world. “People get so excited when they build the bucket, get the test results, and find out what they’re breathing for the first time,” he says. “Man, when they go after companies and regulators, you’d better not be in their way.”

How much you know about silicone and PE pet food lids?

What is the difference between Silicone and PE?


Silicone material has excellent heat resistance, cold resistance, dielectric properties, resistance to ozone and atmospheric aging performance, The outstanding performance is that it can be used in a wide range of temperature, can be in 60 ℃ temperature (or lower) to + 250 ℃ temperature (or higher) use for a long time. It has excellent physiological inertia, non – toxic, tasteless.


PE is non-toxic, tasteless, has good low-temperature resistance (the lowest temperature can reach 70 ~ 100 ℃), chemical stability is good, It can stand most of acid and alkali erosion (acid). PE does not dissolve in solvents at normal temperature, small water imbibition, good electrical insulation performance. Under normal temperature, it is relatively hard, inelastic. When the temperature reaches 80 degrees, it begins to be softening. It will lost the use function at 150 degrees.

Difference Between PE And PVC Plastic Quail Egg Tray

Plastic Quail Egg Tray

  • PVC is actually a vinyl polymer material whose material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, weather resistance, and excellent geometric stability. PVC is highly resistant to oxidizing agents, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid. And it is also not suitable for contact with aromatic hydrocarbons or chlorinated hydrocarbons.
  • Application of PVC: Widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipe, wire and cable, packaging film, bottles, trays, foam materials, sealing materials, fibers, etc.
  • Features of PVC: Hard plastic, often used in industrial fields.
  • Toxicity of PVC: When making soft plastics such as plastic wrap and plastic bags, a large number of auxiliary materials must be added to ensure its safety and Eco-friendly.  
  • Cost of PVC: Its cost is cheaper than PE, so PVC plastic quail egg trays are very suitable for low-cost quail egg packaging.

Plastic Quail Egg Tray

  • PE, the full name of Polyethylene, is the simplest polymer organic compound. It is the most widely used polymer material in the world. It is made of ethylene and is classified into high-density polyethylene, medium density polyethylene and low according to density.
  • Application of PE: plastic wrap, vest-type plastic bag, plastic food bag, bottle, bucket, kettle, etc. It is suitable for making agricultural, food packaging containers and trays and industrial packaging film, wire and cable coating and coating, synthetic paper.
