Is PET packaging better than PVC?

There are significant differences between PVC plastic boxes and PET plastic boxes in terms of material properties, environmental protection, physical properties, application scenarios and costs.

PVC plastic boxes Material nature: Polyvinyl chloride (PVC) is used as the main raw material, and processing performance is improved by adding additives such as plasticizers and stabilizers. Transparency and texture: The transparency is high, but the surface may be slightly bluish or yellowish due to residual additives, and the texture is soft and easy to deform. Chemical stability: It is resistant to acid and alkali corrosion, but it is easy to decompose at high temperatures to produce hydrogen chloride gas, and long-term contact with oil and grease may cause swelling.

PET plastic boxes Material nature: Made of polyethylene terephthalate (PET), the molecular structure is tight and no plasticizer is added. Transparency and texture: The transparency is close to glass, the surface gloss is high, the texture is stiff and not easy to deform. Chemical stability: It is resistant to oil and chemical solvents, does not release harmful substances at high temperatures, and meets food contact safety standards.

Applicable fields of PVC plastic boxes: stationery, toys, low-value daily necessities and other products with low environmental requirements. PET plastic boxes are applicable to: high-end foods (such as chocolate, nuts), medicines, cosmetics, electronic products, etc.

PVC plastic boxes and PET plastic boxes have their own advantages, and the choice needs to be combined with the specific application scenario. If you focus on cost, chemical resistance and hardness, PVC plastic boxes are more advantageous; if you prioritize environmental protection, transparency, food safety and temperature resistance, PET plastic boxes are better
