PVC packaging box is a heat sensitive thermoplastic box that is easy to decompose.
PVC packaging box: as the name implies, it is a kind of general thermoplastic packaging box made of PVC resin. PVC resin is the earliest soft plastic packaging in China and the initial product of plastic packaging in China.The color looks yellowish, translucent and shiny.Transparency is better than polyethylene, polypropylene, the hardness of hard products is higher than low density polyethylene, but lower than polypropylene, in the flexion will appear white phenomenon.
PVC packaging box features:
1. Good comprehensive performance and wide application
2, easy to shape, suitable for a wide range of forming equipment
3. The price is relatively low
4. It has low carbon and environmental protection, and diversified product types
What are the features of PP plastic packaging box?
1. Crystalline material, low hygroscopic, easy to break up, easy to decompose in long-term contact with hot metal.
2. Good liquidity, but large shrinkage range and shrinkage value, prone to shrinkage, indentation and deformation.
3. The cooling speed is fast, the casting system and the cooling system should dissipate heat slowly, and pay attention to the control of molding temperature
4. The thickness of the plastic wall must be uniform to avoid lack of glue and sharp corners to prevent stress concentration.
Material Features:
1, PVC --with nice anti-fouling ability , prices are relatively low.
Mostly used in Daily used goods
2, PET --high transparency & glossiness,beautiful appearance, strong figure
Mostly use in products that required high environmental protection products
3, PP ---good toughness,eco-friendly. Consist smooth PP. frosted PP,twill PP
Mostly use in baby products & stationery products package
What's the difference between a PET box and a regular plastic box?
1. Good mechanical properties, impact strength is 3~5 times that of other films, good folding resistance.
2. Resistance to oil, fat, oleic acid, dilute alkali and most solvents.
3. It can be used in the temperature range of 55-60℃ for a long time, can withstand high temperature of 65℃ for a short time, and can withstand low temperature of -70℃, and the high and low temperature has little influence on its mechanical properties.
4. Low gas and water vapor permeability, excellent gas, water, oil and odor resistance.
5. High transparency, uv blocking, good gloss.
6. Non-toxic, tasteless, good health and safety, can be directly used in food packaging.
This is the difference between PET and ordinary plastic boxes. More comprehensive plastic physical properties are not recommended

Our packaging functions are as follows:
1. Realize commodity value and use value, and increase commodity value.
2. Protect commodities from natural factors such as sunlight, rain and dust pollution, and prevent losses such as volatilization, leakage, melting, pollution, collision, extrusion, dispersion and theft;
3. Bring convenience to storage, transportation, adjustment and sales of circulation links, such as loading and unloading, stocktaking, palletization, delivery, receiving, transshipment and sales counting;
4. Beautify products and attract customers, which is conducive to promotion.
