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.

PVC Clear Egg Trays are widely used in everyday life to hold eggs. The clear egg tray is popular because it is transparent and clean.

 1. What is PVC?

PVC, the full name of Polyvinylchloride, the main component is polyvinyl chloride, and other ingredients to enhance its heat resistance, toughness, ductility and so on. The uppermost layer of this surface film is lacquer.

The density of pure polyvinyl chloride is 1.4 g/cm3, and the density of polyvinyl chloride plastic parts to which plasticizers and fillers are added is generally 1.15-2.00 g/cm3.

Hard PVC has good tensile, flexural, compressive and impact resistance properties and can be used alone as a structural material.

The softness, elongation at break, and cold resistance of the soft polyvinyl chloride increase, but the brittleness, hardness, and tensile strength are lowered.

Polyvinyl chloride has good electrical insulation properties, can be used as a low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCl gas, and discolor the polyvinyl chloride. Therefore, its application range is narrow, and the use temperature is generally between -15 and 55 degrees.

PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other types of plastic products, PVC is more effective in the application of raw materials, reducing fuel consumption. At the same time, the energy consumption of the PVC manufacturing industry is also very low. And in the latter stages of the use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy.

2. Features of the PVC

Molding shrinkage: 0.6-1.5%, molding temperature: 160-190 ° C, melting point 212 ° C.

Excellent mechanical properties, excellent electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Suitable for making thin plates, wire and cable insulation, seals, etc.

Molding characteristics

A. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent bubbles, the plastic can be dried in advance. The mold casting system should be short and thick, the gate section should be large, and there should be no dead angle. The mold must be cooled and the surface should be chrome-plated;

B. Due to its corrosive and fluid characteristics, it is best to use special equipment and molds. All products must be added with different types and amounts of additives as needed;

C. It is easy to decompose. It is more easily decomposed with steel and copper at 200 °C, and it escapes corrosion when decomposed. Irritant gas. The molding temperature range is small;

D. When using the screw injection machine nozzle, the hole diameter should be large to prevent dead angle stagnation. It is best not to have inserts, if there is an insert, it should be preheated.
