PIB CLING MASTERBATCH FOR PE STRETCH FILMS
| INTRODUCTION |
Extruded polymer films are being continually developed for new industrial and packaging applications. Stretch or cling film packaging is a major application for polyethylene. It is dry free flowing pellets. The high PIB content in the polymer matrix achieves the excellent cling properity.
| FOOD STRETCH FILM | PALLET STRETCH FILM | SILAGE STRETCH FILM |
| 8 to 15 µm films thickness | 15 to 25 µm films thickness | 15 to 25 µm films thickness |
| 3 to 7 layers – coextruded structures | 3 to 7 layers – coextruded structures | 3 to 7 layers – coextruded structures |
| Cast and blown film extrusion | Cast and blown film extrusion | Cast and blown film extrusion |
The effects of using cling masterbatch in these films are:
PEEL STRENGTH
High peel cling will prevent unwrapping of the film by friction (Film applied on silage ball need peel strength).
LAB STRENGHT
High lap cling will ensure good interlayer cohesion to the benefit of the holding force and airtight (Film applied on pallet and food stretch film need lap strength).
| CHARACT- ERIZATION | MDCM-765 | MDCM-760 | MDCM-750 |
| PIB | 65% | 60% | 50% |
| Density (g/cm3) | 0.910* | 0.912* | 0.912* |
| Application | pallet, food and silage wrap | Silage, pallet and food wrap | pallet and food wrap |
| Usage in blow film (%) | 6 | 8 | 10 |
| Usage in cast film (%) | 2-3 | 3-4 | 4-6 |
*The data figured out with internal method of Medmonde Chemical.
- MDCB is based on LLDPE carrier, dried and non-sticky pellet.
- MDCB is compatible with LDPE, LLDPE, HDPE, EVA, PP and TPE.
- PE based resin cannot contain any slip or anti-block agent or have a density higher than 0.923 so as not affect the normal exudation of tackifier. Not recommended for use with PE based resin with a density higher than 0.923.
- On multilayer film lines, MDCB-765 is often added to the skin layers only.
- Migration time for good cling properties is 24-72 hours.
- MDCB shelf life is more than 2 years and the product stability in storage is 9 months minimum (based on the temperature).
| PACKING |
