Anti-UV & Anti-Aging Additives
Resist oxidation and aging under outdoor storage and direct sunlight inside containers, doubling service life and ideal for long-distance ocean shipping exposed to sunlight.
Puncture-Resistant Additives
Reinforced tear-resistant molecular layer prevents piercing damage from wooden box edges, metal profiles and sharp hardware corners.
Temperature Modifiers
Stable performance ranging from -20℃ to 50℃, suitable for low-temperature storage in Northern Europe and high-temperature ports in the Middle East.
Eco-Degradable Additives
Custom degradable versions available to meet new EU environmental regulations, satisfying eco-friendly procurement requirements of European & American supermarkets and brand enterprises.
Product Types & Categories
Lightweight rolls with small paper cores for manual stretching without extra equipment. Perfect for small-batch loose goods, small pallets and scattered cargo packing, portable and easy to operate.
Heavy-duty rolls with large cores, compatible with fully automatic and semi-automatic pallet wrapping machines. Higher stretch ratio for mass assembly line packing and full-container pallet loading in factories.
Factory pre-stretched film that requires minimal pulling force by workers, cutting material consumption by 30%. Optimized for high-efficiency packing in overseas warehouses to lower labor costs.
Narrow-width small rolls for partial wrapping of pipes, profiles, express parcels and sharp edges, used with handheld stretch dispensers.

Structural Characteristics
1. 3-layer co-extruded composite structure: Surface wear-resistant layer + middle stretch-tough layer + inner self-adhesive layer, integrally molded with uniform stress distribution to avoid layered cracking, far superior to single-layer extruded ordinary stretch film.
2. Arc edge sealing process: Smooth cut edges free of burrs, preventing hand cuts and edge tearing; no film jamming or breakage under high-speed wrapping machine operation.
3. Tightly wound rolls with high concentricity: Compact winding without looseness, concentricity error ≤1mm, stable film output without deviation or wrinkling during machine operation.
4. Micro-pore breathable structure: Exclusive micro vent design discharges trapped moisture between cargo layers in high-humidity marine environments, reducing mildew and damp damage.
5. Low-residue adhesive formula: Adhesion embedded inside film layers, leaving no glue residue after peeling without corrosion to cartons, plastic and metal product surfaces.

Advantages of Stretch Wrap Roll For Packing
Application Matrix
Standard Production Process
Fully enclosed dust-free production with export-grade standardized control; production traceability reports available for every batch.
2. Constant Temperature Mixing: Automated computer-proportioned mixing and constant-temperature melting stirring to guarantee uniform viscosity and thickness across all rolls.
3. 3-Layer Co-Extrusion Casting: Melting and extrusion via imported casting machines for integrated molding to control film density and stretch toughness.
4. Cooling & Shaping: Gradient water cooling under constant temperature eliminates internal film stress to prevent shrinkage and cracking during later use.
5. Corona Adhesion Treatment: High-precision corona processing for single/double-sided adhesion to accurately control adhesive strength.
6. Slitting & Rewinding: CNC precision slitting to control width and thickness, automatic rewinding to standardize roll weight and concentricity.
7. Custom Printing (Optional): Flexographic customized printing followed by drying and quality inspection.
8. Full Finished Product Inspection: Item-by-item testing for thickness uniformity, tensile strength, elongation at break, adhesive force, puncture resistance, high-low temperature weather resistance, salt fog aging simulation for marine transport and heavy metal environmental testing.
9. Independent Moisture-Proof Packing: Each roll packed in separate PE moisture bag → standard export 5-layer corrugated carton → pallet reinforced with stretch wrap.
10. Warehousing & Shipment: Batch filing, complete customs documents prepared, full-container loading and delivery.

Operation guidelines & Warehouse Standards
Correct Operation Methods:
- Manual wrap: Hold roll and stretch evenly to 1.5-2 times original length for tight cargo fitting; avoid excessive violent pulling.
- Machine wrap: Adjust machine stretch ratio to 200% for general goods; reduce stretch ratio for heavy cargo to prevent film breakage.
- Stacked pallet wrapping: Wrap 4-6 thick layers at pallet base, 2-3 layers in the middle, and 3 waterproof sealing layers on top for maximum stability.
Usage Prohibitions: Keep film away from open flames and high-temperature welding slag. Do not stretch beyond rated stretch ratios to avoid film fracture. Do not directly wrap goods with strong acid or alkali which will corrode the film structure.
Warehouse Storage Standards: Storage environment: 10℃-30℃, cool, dry and well ventilated. Avoid long-term direct sunlight exposure. Pallet stacking height shall not exceed 8 layers. Shelf life is 12 months under original sealed packaging; finish use within 6 months once opened for optimal performance.
