Introduction
Polyethylene terephthalate (PET) is a thermoplastic polyester valued for its mechanical strength, chemical stability, and processability. Widely used in packaging, electronics, and consumer goods, PET faces a critical limitation: inherent surface energy causes material adhesion (“blocking”), reducing production efficiency and end-product quality. INCHR® PET Anti-Block Masterbatch overcomes this through innovative formulation and dispersion technology, eliminating friction and adhesion in PET/BOPET films. It drives packaging innovation across industries.

Food Packaging: Boosting Efficiency & Product Integrity
Challenge: Standard PET films adhere during stacking/transport due to surface tension and static, increasing downtime and defects.
Solution: INCHR® masterbatch integrates micron-sized inorganic particles (e.g., silica, talc) and organic lubricants into PET, creating a micro-isolation layer. This reduces the film’s coefficient of friction to 0.2–0.3 and enhances slip properties.
Results:
✅ 25% increase in packaging line efficiency.
✅ Product loss rate reduced from 2.8% to 0.6%.
✅ Extended shelf life and lower production costs.
Electronics: Precision Protection for Sensitive Components
Challenge: PET adhesion risks dust contamination, scratches, and static damage to delicate electronics.
Solution: INCHR® optimizes dispersion to maintain PET’s transparency/strength while adding anti-static properties and ultra-smooth surfaces.
Results:
✅ 90% reduction in component contamination.
✅ Product qualification rate rose from 92% to 98.5%.
✅ Meets stringent cleanliness standards for semiconductor trays and blister packs.
Daily Chemicals: Elevating Functionality & Consumer Experience
Challenge: Cosmetic/toiletry labels and boxes suffer from stacking adhesion and poor ink adhesion.
Solution: Precise surface roughness control via anti-block masterbatch enables easy peeling and vibrant print adhesion.
Results:
✅ 30% faster label laminating efficiency.
✅ 78% user satisfaction with packaging openability.
✅ Enhanced shelf appeal and brand competitiveness.
Future Innovations: Eco-Friendly & High-Performance Solutions
As demand grows for functional film materials, INCHR® advances its masterbatch technology toward:
🌿 High dispersion & low dosing (reducing material use).
♻️ Eco-friendly formulations for circular economies.
🔮 Applications in smart packaging (e.g., RFID-integrated films).
Conclusion
INCHR® PET Anti-Block Masterbatch revolutionizes PET film performance across critical sectors. By eliminating adhesion, boosting efficiency, and ensuring product quality, it enables next-generation packaging solutions—proven by industry-leading adoption in food, electronics, and consumer goods.
