food plastic packaging materials milk coffee powder bag material package
There are many different materials of the film,such as BOPP Alu 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/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) |
Each materials characteristics:
| English name | how to distinguish and its characteristics | material rate |
| 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 |
Bag type these material can make:
