Why do foam mattress manufacturers need to use peelable PE-coated kraft paper?
Jun 11, 2025
What is Peelable PE-Coated Kraft Paper?
Peelable PE-coated kraft paper is a laminated industrial paper made by coating kraft paper with a thin layer of polyethylene (PE) film. The PE coating provides a smooth, non-stick surface that allows foam materials to release easily during manufacturing.
Depending on application needs, peelable PE-coated kraft paper may be:
Single-sided or double-sided PE coated
Different thicknesses of kraft base paper (30gsm~120gsm common)
Customized peel strength (easy-peel, standard peel, or tight peel)
Why Do Foam Mattress Factories Need It?
1. Easy Demolding During Foam Curing
Foam mattresses (PU foam, memory foam, latex foam, etc.) are produced through chemical reactions that expand and cure the foam. During curing, the foam is poured into molds or continuously foamed into large blocks.
Without a release layer, the foam would stick to the mold surface, leading to:
-Damaged surface finish
-Irregular shape
-High scrap rate
The peelable PE-coated kraft paper creates a clean separation layer, allowing the cured foam to be easily removed without tearing or surface defects.
2. Protects Foam Surface Quality
The smooth PE layer prevents surface imperfections, ensuring:
Uniform, clean foam block surfaces
Improved product appearance
Less secondary trimming and waste
This is especially important for high-end memory foam and premium mattresses where surface uniformity matters.
3. Keeps Mold and Equipment Clean
Foam residues on mold surfaces can cause:
-Cross-contamination between batches
-Process downtime for cleaning
-Equipment wear and maintenance costs
Using peelable kraft paper reduces mold fouling and extends equipment life.
4. Improves Production Efficiency
Faster demolding = shorter cycle times.
Less cleaning = more uptime.
Lower scrap = higher yield.
Cleaner product surface = fewer defects.
All of these contribute to lower production costs and higher profit margins.
5. Customizable for Specific Production Needs
Different foam formulations may require different release properties:
Some require higher peel strength for tight foam adhesion.
Some need ultra-low peel strength for delicate foam types.
Some may require anti-static or breathable coatings.
High-quality peelable PE-coated kraft paper suppliers can customize the product for your exact process needs.
hat Happens If Low-Quality Release Paper Is Used?
Choosing cheap or poor-quality PE-coated kraft paper can cause:
-Film wrinkling during curing
-Uneven foam surfaces
-Tearing or paper residue on foam
-Dimensional defects
-Unexpected machine stops
For large-scale mattress manufacturers, the cost of defective release paper far outweighs any small savings on material cost.
