Recyclable Plastic BOPP PET PE CPP Powder Packing Material
There are many different materials of the film,such as BOPP PET PE CPP PE+PET,OPP,PE and so on,
different material suitable for different packing product, contact us to show you the
material suitable for you.
Package Material List and Its Application:
| Material Name | Application range |
| BOPP /CPP | Packaging bags for past food and daily necessities |
| BOPP /LDPE | |
| BOPP/CPP | The inner layer is a packaging bag made of pure aluminum foil or Fufu film, which is mainly used for moisture proof, puffed food, dry goods, etc |
| PE/CPP | |
| BOPP/PET/PE or CPP | Aluminized bag |
| PET /PET /PE or CPP | Aluminized bag |
| BOPP / LDPE | Foil bag |
| PE /LDPE | Aluminum foil bag (commonly used aluminum foil bag compound method) |
| Coatd BOPP /LDPE or CPP | Mainly used for products that need to maintain fragrance |
| Coatd PET /LDPE or CPP | |
| Nylon / LDPE or CPP | For food that needs to be refrigerated |
| PET/LDPE or CPP | |
| PET/Nylon/LDPE or CPP | |
| Nylon / Cooking type CPP | For products requiring high-temperature cooking |
| PE /Nylon or CPP | |
| PET/Nylon/Cooking type CPP |
Each materials characteristics:
| English name | how to distinguish and its characteristics | material rate |
| HDPE | White and transparent, several layers will appear white, after biting with teeth, there will be white razor marks at the crack, the material is relatively brittle, hard, and the rate of expansion and contraction is low. The sound is crisp when rubbing, some areas also call HDPE as PO material, LDPE is called P electricity to distinguish | 0.94-0.97 |
| LDPE | White transparent, more grainy, good initial twist, good transparency, smoother feel, the material becomes harder. The expansion rate is large, when the sound is twisted, there are some areas where HDPE is called PO material, and LDPE is called PE material. distinguish | 0.91-0.93 |
| LLDPE | Similar performance to LDPE film but high strength | 0.91-0.93 |
| OPP | The body is very brittle, the transparency is high, the tension is not strong, but it is easy to burst, and the printing is easy to discolor | 0.91 |
| PVC | The material body is soft or hard, and also has transparent material, ordinary material and frosted material. The pulling force is not easy to rip. It is also not easy to burst, flame retardant, the product is flexible and tough, and the feel is sticky. Polyethylene, which is lower than polypropylene, will be whitened at the inflection point | hard 1.35-1.45 soft 1.16-1.35 |
| PP | The body is brittle. But the transparency is relatively high. It is clearer, the pulling force is not very good, and it is easy to burst | 0.9-0.91 |
| CPP | High transparency, higher stiffness than PEJW film, often used as composite base film | 0.9 |
| PET | Good transparency. The strength and toughness are better than polystyrene and PVC, not easy to break, and the surface is smooth and shiny | 1.4 |
| PA | Often making steamed / boiled bag composites |
1.15 |
| EVA | The surface is soft; the tensile toughness is stronger than LDPE, and the feel is sticky (but the surface is free of glue); the white is transparent and the transparency is high. The look and feel are very similar to the PVC film | 0.91-0.93 |
