Outline

Stress crushing characteristics·Transparency·Many properties of the CPP(polypropylene), PE(polyethylene), but similar to the tensile strength than PE (polyethylene), and is excellent.

Characteristic

- Lightweight characteristics

Belongs to the plastic of the proportion of small classes.

- PP distinctive characteristics of hinge

Has repeated that "it is stronger in bending hinge characteristics".

- Food hygiene

FDA hygiene compliance.

- Crushing goes well on the stress.

- Good surface appearance

Surface gloss, relatively difficult to wound.

Applications

Automobile parts, household electrical parts, tableware·Stationery Supplies·Tabletop·Office Supplies· Medical courage·Goods flow container, food packaging film, fiber material, Flat Speakers.
