Grade:
1. Blow molding grade,
2. Injection molding grade,
3. Film grade;
4. Extrusion grade.
Application:
Fiber (Carpet, Textiles, Upholstery, etc. )
Film (Shopping bags, casting film, multilayer film, etc. )
Blow Molding (Medical & Cosmetic container, Lubricant & Paint container, etc)
Extrusion Molding (Sheet, Pipe, Wire & Cable, etc. )
Injection Molding (Automotive, Electronic, Construction, House wares, Furniture, Toys, etc. )
LLDPE Applications:
1. Film applications such as food and non-food packaging, shrink/stretch film and non-packaging uses. (The trend in food packaging films is towards high performance film structures that are less permeable to increase shelf life and enhance flavours).
2. Other film applications such as ( using metallocene or single site catalyst technology) multi-layer cast stretch film, agricultural greenhouse film, saran wrap, bubble wrap, medium to heavy duty bags, lamination packaging film and multilayer film barriers used in drink cartons.
3. Extrusion coating applications where it helps protect the contents of liquid containers, primarily for paper and paperboard packaging.
4. Injection moulding sector has outlets such as lawn and garden products, kitchen accessories, luggage and furniture parts, recreational products and toys.
5. Non -food packaging applications are requiring stronger films such as consumer, industrial and agricultural uses.
6. Plastic bags and sheets (where it allows using lower thickness than comparable LDPE), plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables, geomembranes, and mainly flexible tubing.
