材料简述：

---

TS9022 is a low density polyethylene (LDPE), developed specially for automatic overwrap packaging. This resin has a combination of high optical properties and excellent stiffness. The incorporated additive package consists of an antiblocking agent in high level and a slip agent in medium level, to guarantee a low coefficient of friction (COF), which fundamental for improved machineability in overwrap applications. This product is identified as PE 123 according to ASTM D- 4976-04a standard specification.

Additivation:
Antiblocking agent
Slip agent

Application:
Films for automatic overwrap packaging of hygiene markets. Typical applications are toilet tissue, kitchen paper, and napkin (paper products) overwrap.
Laminated films for food packaging with (PP or BOPP), for products such as coffee, crackers, and powder milk.
Films which require good optical proprieties aligned with high stiffness.

Process:
Blown Film Extrusion
