Typical Applications
Paper and Paperboard Coating
Moisture barriers and packaging layers for cups, cartons and coated papers.
Aluminum Foil Lamination
Flexible packaging structures requiring controlled adhesion and processing.
Woven Fabric Coating
Coated woven sacks and industrial fabrics requiring coverage and bonding.
Multi-Layer Packaging
Extrusion-coated or laminated structures coordinated with primers, substrates and converting conditions.
Grade Selection Factors
The following factors are application references, not guaranteed specifications. Final selection must be confirmed using the current producer TDS, COA and customer requirements.
| Selection Item | What to Confirm |
|---|---|
| Melt strength and drawdown | Match coating speed, die width and target coating weight. |
| Oxidation and adhesion | Review air gap, melt temperature, substrate treatment and primer use. |
| Neck-in | Confirm acceptable edge reduction and line setup. |
| Odor and compliance | State food-contact or other regulatory requirements where applicable. |
Information Needed for Quotation
Substrate, primer or treatment, line speed, coating weight, die width, current grade, adhesion target, compliance requirement, quantity and destination port.
Frequently Asked Questions
Is ordinary LDPE film grade suitable for extrusion coating?
Not necessarily. Coating grades are selected for drawdown, neck-in and adhesion behavior.
Can you match a coating grade from a datasheet?
Yes. Provide the datasheet and line conditions.
Is food-contact compliance automatic?
No. Confirm the exact producer declaration and destination-market requirement.
