Data from ExxonMobil Chemical.

Application:Heat sealable cPP lamination film for food, non-food and stationary product packaging. Hermetic seals for MAP.

Key points:• Improved sealing performance

- Low and very low seal initiation temperature

- High hot-tack force

- Expanded range of sealing temperatures to improve hermetic seals

Testing on HFFS packaging machine indicates:• Much wider operating range compared to

terpolymer sealant. Valuable when:

- accurate heat control is a problem

- dwell times vary because of frequent machine speed changes

• Much faster line speeds are achievable

- production output can be doubled without adding a new machine

New PBEA new Versatile Polyolefin for Extrusion Coating Applications

12

Extrusion Coating Applications These inherent attributes of New PBE

• Exceptional adhesion to PP substrates

• Very low temperature sealing, high seal strength

• Increased flexibility and softness

• Elasticity

• Toughness

• Anti-skid (high COF)

• High gas permeability

• Polyolefin / recyclable structure (non-PVC)

Can be applied to these structures …• Extrusion laminations for food packaging

• Oriented polypropylene film coatings

• Document plastification / thermal laminations

• Industrial fabric coatings

• Extensible coatings onto nonwoven fabrics

• Coatings onto woven PP fabrics

• Elastic laminates

13

Key Benefits• Better bond strength vs. hPP & RCP

• Downgauging of the coating layer

• Lower SIT and welding temperature

• Higher UV resistance vs. hPP

• Controlled anti-skid for better pallet stability

• No shrinkage in seal areas results in improved bag appearance

• Good blend partner with PP and PE

• Easy processing on conventional extrusion coating line

• Excellent coextrusion with other PO’s

The vertical axis gives the angle at which a weight covered by the coated fabric starts sliding on an inclined surface covered with the same coated fabric. The higher the angle, the higher

are the anti-slip properties of the coating (measures done based on ASTM D 202).
