PP resin stands for Polypropylene, which is a polymer, a product of Propylene polymerization.

Characteristics of PP resins

High mechanical strength (tear strength and tensile strength), quite rigid, not as flexible as PE, not stretched and therefore made into fibers. Especially easy to tear easily when there is a cut or a small puncture. Transparent, high surface gloss for high printing ability, clear print. PP colorless, odorless, tasteless, non-toxic. PP plastic burns brightly with a light blue flame, has a flexible flow, has a burning smell similar to that of rubber.

Application of PP resins

Used as a single-layer packaging for food preservation, does not require strict anti-oxidation. Formed into fibers, woven into food packaging, bulk cereals. PP resins are also produced as laminated films to increase the air, steam, water-proofing properties, and to tear open the packaging (due to the creation of a cut). and create a high gloss for packaging.
