An estimated 8 million metric tons of plastic pour into the oceans every year, amounting to the equivalent of one garbage truck every minute, USAID Counselor Chris Milligan told a crowd at the Wilson Center in Washington, D.C., said on August 8th, 2019. This makes us feel the need for plastic recycling again.

There are now five massive patches of floating garbage in the world’s oceans. We found microplastics in the Arctic Sea ice, at the most remote stretches of islands in the Pacific and in the deepest ocean trenches.

Most ocean plastic comes from land-based sources, said Counselor Milligan:
An enormous amount comes from cities in the developing world which cannot adequately manage their waste. This includes a number of cities in the rapidly urbanizing countries of South and Southeast Asia. Ocean plastic waste is a global problem, but waste management is a local issue. It is not difficult to see from his speech-plastic recycling is a practical and necessary method.

*What is plastic recycling？

Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products. Since the vast majority of plastic is non-biodegradable, recycling is a part of global efforts to reduce plastic in the waste stream, especially the approximately 8 million metric tonnes of waste plastic that enters the Earth’s ocean every year.

*Plastic Recycling Logos

The plastic recycling logo was established by the Society of the Plastics Industry (now renamed Plastics Industry Association) in 1988. This set of logos will be plastic material identification code on the container or packaging, from No. 1 to No. 7, so that people do not need to bother to learn the similarities and differences of various plastic materials, can simply join the ranks of recycling work. Each plastic container has a small ID card – a triangular symbol, usually at the bottom of the plastic container. There are 1 to 7 numbers in the triangle. Each number represents a plastic container. They are made of different materials and different taboos.

* plastic recycling symbols meaning

Plastic recycling No. 1 PET

PET (polyethylene terephthalate), a container made of this material, is a common plastic bottle for soda, also known as bottles.

Qiming Packaging PET products are as below:

Besides that, common mineral water bottles, carbonated beverage bottles also made from PET. It is easy to deform from heat resistance to 70 C, and has substances harmful to the human body to melt out. The carcinogen DEHP may be released from No. 1 plastics after 10 months. Qiming Packaging recommends you not put it in the sun or in the car or fill it with alcohol, oil, etc.

Plastic recycling No. 2 HDPE

HDPE (high density polyethylene), detergent, shampoo, bath milk, edible oil, pesticides and other containers are mostly made of HDPE.

Qiming Packaging HDPE products are for your reference

Qiming Packaging suggest you not use it as a water cup . Don’t recycle if it’s not thoroughly cleaned.

Plastic recycling No. 3PVC

PVC (polyvinyl chloride), mostly used in the manufacture of water pipes, raincoats, schoolbags, building materials, plastic film, plastic boxes and so on.

Qiming Packaging PVC  products are as followings

Because of its excellent plasticity and low price, it is widely used and can only resist heat at 81 C. It is easy to produce bad substances at high temperature, and seldom used in food direct packaging.Qiming Packaging reminds you not to buy drinks if they are packed by PVC.Like an egg with a shell, you can rest assured to use a PVC tray.

Plastic recycling No. 4 LDPE

LDPE (Low Density Polyethylene), plastic bags everywhere are mostly made of LDPE.

The fresh-keeping film, plastic film, etc. When high temperature occurs, harmful substances are produced. When toxic substances enter the human body with food, they may cause breast cancer, congenital defects of newborns and other diseases. Qiming Packaging advice you are not put the LDPE film in the microwave oven.

Therefore our LDPE products are non-food ones,Qiming Packaging focus on LDPE plastic end caps plugs covers for pipes ,flanges and valves.

Plastic recycling No. 5 PP

PP (polypropylene) is used to make water cans, garbage cans, baskets, food containers for microwave ovens and so on.

Common soybean milk bottles, yogurt milk bottles, juice beverage bottles, microwave oven lunch boxes. It can withstand high temperatures up to 167 degrees Celsius. It is the only plastic box that can be put into the microwave oven. It can be reused after careful cleaning. It should be noted that some microwave oven lunch boxes are made of No. 5 PP, but the lid of the box is made of No. 4 PE. Because PE can not withstand high temperature, it can not be put into the microwave oven with the box body. Our Qiming Packaging food grade PP container as below for your reference.

Plastic recycling No. 6 PS

PS (polystyrene), because of its low water absorption, is mostly used to make building materials, toys, stationery, rollers, as well as drink cupboxes or disposable tableware in fast food stores.

Plastic recycling No. 7 OTHER

Other. Common PC categories, such as kettles, space cups, milk bottles. Department stores often use water cups made of this material, PA, or nylon, for the internal parts of textile fibers and some household appliances. PC is easy to release toxic substance bisphenol A at high temperature, which is harmful to the human body. So Qiming Packaging reminds you when using, do not heat or do not direct sunshine.

Our goal is to provide our customers the recycling plastic so that they can participate in the world economy as equals and be bettering in addressing global challenges. （This article is written by Qiming Packaging Lynette, if copy request, please indicate the source or contact mail@qiminggroup.com for more exchanges.）If you want to know more about our products or do not find the one you are looking for,you may visit us the other website.

Are PVCs dangerous? Can you use it with confidence? Many people may have that doubts. After all, PVC is quite common in our daily life. This post mainly analyses the composition and raw materials. We hope to have a little help in solving your confusion.

The following picture must be familiar, right? It’s the most common PVC packaging. Let’s first understand the definition to see if we can get the answer to “Are PVCs dangerous”.

Polyvinyl chloride (PVC) is also a commonly used plastic. It is a resin composed of PVC resin, plasticizer, and antioxidant. It is not toxic in itself. But the plasticizers and antioxidants are toxic. The plasticizers used in daily polyvinyl chloride plastics are mainly dibutyl terephthalate and dioctyl phthalate. These chemicals are toxic. The antioxidant lead stearate of polyvinyl chloride is also toxic. Lead precipitates from PVC products containing lead salt antioxidants in contact with ethanol, ether, and other solvents. Lead-containing polyvinyl chloride (PVC) can be used as food packaging when it meets fried sticks, fried cakes, fried fish, cooked meat products, and cake snacks, which will cause lead molecules to diffuse into grease. Therefore, PVC plastic bags can not be used to hold food, especially oily food. In addition, polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at high temperatures, such as about 50 degrees Celsius. This gas is harmful to the human body, so polyvinyl chloride products should not be used as food packaging.

PVC is divided into soft PVC and hard PVC. Because soft PVC contains softener, it is easy to become brittle and difficult to store, so its scope of use has been limited. Hard PVC does not contain softener, so it has good flexibility, easy to form, is not brittle, is non-toxic and non-polluting, and it also has a long storage time, therefore it has great development and application value.

The PVC industry is developing rapidly in the world and has broad prospects. All countries are optimistic about the potential of PVC and its benefits to the ecological environment. PVC is demonstrating its role and status to the world with its superior and unique performance, which cannot be replaced by any other products. Social development needs it, environmental protection needs it, it is an inevitable trend of the progress of our human society.

For example, some common PVC material packaging materials in the supermarket like egg trays, quail egg trays, and fruit trays, etc. They are all PVCs.

In a word, PVC is a kind of polymer of chlorine and acetylene. PVC itself is non-toxic at room temperature. But only when PVC is used at high temperatures or when it is processed with toxic additives can PVC be harmful to the human body. In general, drinking or eating high-temperature objects is not recommended to contact PVC products. We guess that you have a deeper understanding of this question-“Are PVCs dangerous?”.

Our PVC products, like egg trays and quail egg trays, don’t touch food directly. So there’s no danger. PVC material is very stable at room temperature and does not release toxic substances.

Blister packaging: a general term for the production of plastic products by the blister process and packaging of the products with the corresponding equipment. Blister packaging products mainly include blister, tray, plastic box, synonym: vacuum cover, blister and so on. Blister pack equipment mainly includes a plastic molding machine, punching machine, sealing machine, high-frequency machine, folding machine. The packaged product formed by the package can be divided into the card, suction card, double bubble shell, half bulb shell, double folded bulb shell, three fold bulb shell and the like.

Blister: A plastic processing technology. The main principle is to heat and soften the flat plastic sheet. It is vacuum-adsorbed on the surface of the mold and cooled to form. It is widely used in plastic packaging, lighting, advertising, decoration, and other industries.

Bubble shell: The transparent plastic hard sheet is made into a transparent plastic with a specific convex shape by a blistering process, and covers the surface of the product to protect and beautify the product. Also known as a blister, vacuum cover.

Blister mold: mold for plastic production, the lowest cost is plaster mold, followed by electroplated copper mold, the most expensive is aluminum mold. The mold is drilled with small holes for vacuum adsorption of the heated hard sheets to form a blister product.

Blister molding: It is the blister that we often talk about. The plastic soft sheet that is softened by heating is absorbed on the surface of the mold by a plastic forming machine, and after cooling, plastic having a concave-convex shape is formed.

Blister cutting: plastic products after plastic forming, through the punching machine, the large sheets are cut into individual products by knife die.

Folding: The three sides of the blister are folded to the back with a folding mechanism so that in the next packaging process, the paper card is inserted into the hem to form a card package.

Heat sealing: It is a blister packaging process. The paper card coated with blister oil is heat-sealed together with a blister by a sealing machine to form a blister card package.

High-frequency sealing: It is a blister packaging process. A high-frequency machine is used to generate high-frequency, and the blister and the blister are bonded together to form a double blister package.

In our daily life, many products are made by blister processing, such as PVC transparent egg tray, quail blister egg tray, fruit tray and so on.

The important environment of environmental protection is the basic premise of human survival &development. Which plastics can you put in the recycling bin? You’re an eco-conscious individual – you try to use less of what you can and recycle what you do. But when it comes to plastics, just what can you recycle? Some, like 1L soda bottles, are obvious, but what about milk bottles? Or blister packs? What about plastic bags?

Fortunately, that little on the bottom of your plastics can tell you a lot about how to dispose of them properly. So if you’re wondering if you can throw your take-out boxes in the recycling bin, refer to this handy guide:

#1 – PET

PET is one of the most widely used and recycled plastic resins. Found in plastic drink bottles and microwavable food trays, most can be disposed of in standard curbside recycling bins. So PET is the plastics which can put in the recycling bin

We always use PET jars to pack candies, dry fruits and nuts.The PET jars from Qiming company have high quality.

#2 – HDPE (High-Density Polyethylene)

HDPE is a resilient plastic film commonly used in plastic grocery bags, as well as drink bottles (notably milk jugs), and non-food containers (such as those for shampoo or detergent). Plastic grocery bags are notoriously hard to recycle, and for the most part, can only be recycled by bringing them back to the store, but other HDPE products can be left in the curbside recycling bin as well.

The material of Jerry cans from Qiming is PE. Various sizes can meet different requirements 

#3 – PVC

PVC is another strong plastic that’s highly resistant to impact and grease and oils, found commonly in meat wraps, medical packaging, pipes, and blister packs/clamshell packaging. Unfortunately, PVC is a very difficult plastic to recycle, and due to the chemicals used in its manufacture, even a small amount can contaminate up to a half ton of recycled plastic. Check with your local recycling firms before depositing PVC products in your recycle bins.

The material of egg trays from Qiming is PVC. Various sizes can meet different requirements.

#4– PP (PolyPropylene)

Among other uses, PP is most commonly used as bottle caps for plastic bottles. Unlike the PET bottles, though, PP caps cannot be recycled in the same process. While some municipalities (for example, the majority of California), will accept #5 plastic in their curbside recycling program, double-check beforehand and always remove the caps from your bottles first. Plastic buckets, Round, square and rectangle are all available. So PP plastics put in the recycling bin.

#5 – Other

Given the miscellaneous nature of plastics in this category, almost no municipal recycling program will accept #7 plastic in their curbside bins. On the other hand, biodegradable plastics fit into this category. These plant-based plastics can only be composted in an industrial composting recycling facility, though, so contact your local composting center for more information on how to properly dispose of these plastics.

And all Qiming plastic product belongs to recycled standards. Should have any other interest, please contact us to discuss more.
