HDPE Cotton Wrap Film – UV Resistant For Outdoor Storage (6–18 Months In

Our HDPE cotton wrap film provides superior UV protection for industrial cotton bales, ensuring long-term outdoor storage. The film combines high tensile strength, flowable multilayer structure, pre-sealed tail ends, and edge coverage to prevent cotton scattering and water ingress. Embedded RFID tags are included for optional digital tracking, but the main focus is on durability and UV resistance.

Each roll wraps 24 cotton bales (~100 kg per bale) and is suitable for mechanized and manual operations.

Cotton bale storage and packaging face several challenges:

• Limited outdoor storage: Cotton in fields or open environments is vulnerable to high temperatures and heavy rain.
• Tail end adhesion issues: Conventional films fail to seal properly, leading to scattered bales.
• UV degradation: Films without UV stabilization degrade, discolor, or weaken under sunlight.
• Water ingress: Incomplete edge coverage (15–20 cm at top/bottom) allows rainwater to penetrate.
• Mechanical tearing: Low tensile strength (<20 MPa) causes tearing during wrapping.
• Flow issues: Non-optimized multilayer films reduce wrapping efficiency and can cause jams.

These problems are caused by:

• Weak adhesive formulations at the tail end.
• Lack of UV stabilizers leading to rapid degradation outdoors.
• Insufficient edge coverage exposing cotton to rainwater.
• Low tensile strength in competitor films.
• Simple blown films without optimized multilayer flow structure.
• Poor protection against high temperatures and moisture in outdoor environments.

Our 5-layer HDPE cotton wrap film addresses these challenges:

• UV protection (6–18 months in Australia & Brazil) ensures bales maintain integrity in outdoor storage.
• Pre-sealed tail end secures the film, preventing cotton scatter.
• Edge coverage 15–20 cm protects against rainwater and moisture ingress.
• High tensile strength ≥30 MPa prevents tearing during wrapping.
• Flowable multilayer A+B structure with self-adhesive formulation ensures smooth, efficient wrapping.
• Optional embedded RFID tags allow digital inventory tracking.

Each roll reliably wraps 24 cotton bales (~100 kg each), with consistent field performance.     

• Field and warehouse cotton bale packaging
• Long-distance transport protection
• Prevention of cotton explosion and water ingress
• Agricultural product protection requiring tear-resistant, moisture-proof, UV-stable film
• Optional digital tracking via RFID tags

• Wraps tightly around cotton bales to protect against scattering and moisture.
• Pre-sealed tails and edge coverage prevent rainwater ingress.
• UV-resistant additives maintain film integrity and color during outdoor storage.
• Flowable multilayer structure ensures smooth mechanized or manual wrapping.
• Optional RFID tags provide real-time inventory tracking.
