PVC packaging refers to packaging products made of polyvinyl chloride material. PVC is a common plastic with good plasticity and weather resistance. PVC packaging products usually have the characteristics of softness, transparency, durability, waterproofing, weather resistance, heat insulation, and sound insulation. The transparency is better than polyethylene and polypropylene. The hardness of hard products is higher than low-density polyethylene but lower than polypropylene. There will be a whitening phenomenon. Widely used in a variety of packaging fields.
The performance characteristics of polyvinyl chloride (PVC) are:
- Crystal clear. Poor impact resistance, hard (will become soft after adding plasticizer);
- Good aroma and taste retention, excellent barrier properties to oxygen, water, oil, alcohol, petroleum, and solvents;
- Not easy to be corroded by acid and alkali;
- Polar. Therefore, it has a strong affinity with other additives, and can be made into PVC products with different toughness;
- Susceptible to aromatic hydrocarbons, halogenated hydrocarbons, ketones, esters, acids, nitrogen, sulfur, and phosphorus molecules;
- It will turn yellow when exposed to heat and ultraviolet rays for a long time, and it will decompose when overheated (136°C), and produce corrosive substances;
- It is required that the content of monomers (harmful to the human body) in the material should be stable, so there are strict restrictions on the use of food packaging;
- When dealing with PVC, there are environmental issues, such as the burning of PVC will produce HCl (some even suspect that chlorinated dioxins will be produced).
Advantages of PVC packaging
- Good plasticity PVC material has excellent plasticity, which can be made into various shapes of packaging products to meet different packaging needs.
- Durable PVC packaging products have high durability and can withstand certain pressure and impact to protect the packaged items from damage.
- Waterproof PVC packaging products have good waterproof performance, which can effectively prevent packaged items from getting wet.
- Transparent PVC packaging products have good transparency and can clearly display the appearance and characteristics of the packaged items.
- Good heat insulation performance PVC packaging products have good heat insulation performance and can effectively maintain the temperature of the packaged items.
- Good sound insulation performance PVC packaging products have good sound insulation performance and can effectively isolate external noise.
Features of PVC packaging box:
- The overall performance is good, and it is widely used
- Easy to form and suitable for a wide range of forming equipment
- Low-carbon and environmentally friendly, with various product types
- High hardness, good stiffness, and strong load-bearing capacity, compared with other materials, it has high corrosion resistance, compression resistance, and folding resistance, and can well protect internal products.
The function of PVC packaging box:
- The PVC packaging box can protect the internal products well, which is better than the previous paper packaging boxes;
- The PVC packaging box has good waterproof, moisture-proof, and sun-proof properties, which is suitable for protecting internal products under adverse environmental conditions;
- The PVC packaging box is exquisite in workmanship, which can improve the grade of internal products;
- Exquisite printing of PVC packaging boxes can increase the added value of packaging products. Screen printing, offset printing, bronzing, and hot stamping can be directly performed on the surface to maximize the charm of the product, shape the product image more intuitively and effectively, and improve product quality. Added value has become a new way to lead the packaging trend.
- PVC plastic packaging boxes are all made of transparent materials so that the items in the plastic box can be seen intuitively, which is not only beneficial for us to store and take, but also gives the items an intuitive display opportunity, and can improve packaging and The grade of the item.
Material properties of PVC packing box
PVC packaging box material 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 and concentrated nitric acid, and it is also not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. The melting temperature of PVC is a very important process parameter during processing. If this parameter is not appropriate, it will lead to the problem of material decomposition. The flow characteristics of PVC are quite poor, and its process range is very narrow. In particular, PVC materials with large molecular weights are more difficult to process (such materials are usually added with lubricants to improve flow characteristics), so PVC materials with low molecular weight are usually used. The shrinkage of PVC is quite low, generally 0.2~0.6%.
The environmental protection performance of PVC packaging
The environmental protection performance of PVC packaging products has also received much attention. On the one hand, the PVC material itself has good recyclability, which can reduce the impact on the environment through recycling and reuse. On the other hand, PVC packaging products can effectively protect packaged items and reduce damage to packaged items during use, thereby reducing the impact on the environment. At the same time, PVC packaging products can also use environmentally friendly materials and production techniques in the production process to reduce environmental pollution.
