Industrial Logistics and Transport Packaging
Stretch film accounts for up to 60% of the logistics industry's usage (Source: 2023 Global Packaging Association Report). Its main functions include:
1. Pallet Securing: Stretch film is wrapped mechanically or manually to prevent cargo from collapsing during transport. A single roll of standard film (50cm wide, 1500m long) can cover approximately 20 standard pallets.
2. Dust and Moisture-Proofing: Stretch film offers a strong seal, blocking rain and dust, making it particularly suitable for transporting electronics in sea containers.
3. Cost Optimization: Stretch film can reduce packaging costs by 30% compared to traditional strapping (US Transportation Security Administration case study).
Agricultural and Horticultural Protection
1. Silage Wrapping: Specialized black and white stretch film isolates silage from oxygen, extending its shelf life to up to 18 months (according to experimental data from the Netherlands Agricultural Technology Center).
2. Greenhouse Insulation: Transparent stretch film is used for greenhouse coverings, achieving a light transmittance of over 90% while also reducing heat loss.
Food Preservation and Retail
1. Fresh Produce Packaging: Supermarkets often use PE stretch film for fresh meat, fruits, and vegetables. It has a thickness of less than 0.01mm and meets FDA food safety standards.
2. Food and Beverage Protection: During the pandemic, stretch film was used to seal buffet tables to prevent droplet contamination.
Building Material Protection
1. Scratch Protection for Panels: Stretch film is used to protect marble and glass surfaces during renovations, with an impact resistance of up to 5kg/cm² (building materials industry testing standard).
2. Temporary Waterproofing: Stretch film can be used during roof repairs to withstand short bursts of heavy rain (waterproof rating IPX4).
Home and Daily Uses
1. Moving and Organizing: Use stretch film directly to wrap items in drawers to prevent them from falling apart.
2. DIY Reinforcement: Creative uses have been found by netizens, such as securing carpet edges and making makeshift phone holders.
Special Industry Applications
1. Medical Sterilization: Medical-grade stretch film is used for sterilization and packaging of instruments and requires ISO 11607 certification.
2. Aerospace components: Carbon fiber reinforced stretch film is used for transporting aircraft parts, with a temperature resistance range of -50°C to 120°C.
