1.What is the difference between PVC and PET?
Polyvinyl chloride (PVC): Plasticizers and stabilizers are usually added to regulate its flexibility.
Polyethylene terephthalate (PET): Polyethylene terephthalate, a polyester polymer.
1. Environmental protection performance: PVC contains chlorine, which will produce harmful gases (hydrogen chloride) when burned. Some plasticizers are not environmentally friendly. PET does not contain chlorine, is environmentally friendly and recyclable, which is more in line with the international environmental protection trend.
2. Hardness: PVC is relatively soft and flexible, and the scratch resistance level is 1H. PET has higher hardness, stronger rigidity, is not easy to deform, and the scratch resistance level is 3-4H.
3. Heat resistance: PVC has poor heat resistance and will deform at about 60-80℃; while PET has better heat resistance and can withstand a high temperature of about 150℃.
4. Cost: PVC raw materials are cheaper and processing is more convenient; while PET raw materials and processing costs are higher.
5. Printing/coating performance: PVC is easy to process and color, suitable for low-end decorative film. The surface tension of PET is high and requires corona/coating treatment, but the finished product is more exquisite.

2.What is the difference between PET and PETG?
PET (polyethylene terephthalate)
Polyethylene terephthalate (PETG) is a crystalline polyester.
PETG (ethylene glycol modified polyethylene terephthalate)
PETG is modified by adding ethylene glycol to prevent partial crystallization, making it softer and easier to process.
1. Environmental performance: PET and PETG are both recyclable environmentally friendly new materials.
2. Production process: Our PET is a two-way stretch PET (BOPET), which adopts a two-way stretch production process; while PETG is extruded and coated, so PET has better scratch resistance.
3. Our PET is a two-way stretch PET (BOPET). PET is stretched vertically and horizontally during the production process, and its scratch resistance is slightly better than that of PETG. PETG is stretched and extruded longitudinally before coating. PETG adopts a three-layer GAG structure, so it can better control the color difference.
4. Application: Our PET is usually processed into a transparent film with a hardness of 3-4H, and PETG is processed into a color film. The chromatic aberration control rate between different batches can reach ΔE<1, and there is almost no chromatic aberration.
