english What's the Shelf Life of PE Protective Film Roll

PE Protective Film Shelf Life Guide
The shelf life of a PE protective film roll typically ranges from 12 to 24 months when stored properly, though this can vary based on material quality and storage conditions. Manufacturers often specify a 18-month window as standard, assuming ideal storage—cool, dry environments away from direct sunlight and extreme temperatures.
Key factors influencing longevity include:
- Adhesive stability: The pressure-sensitive adhesives in PE films can degrade over time
- Film integrity: Especially when exposed to heat (above 30°C/86°F) or humidity
- UV exposure: Radiation breaks down the PE polymer structure
Ideal storage temperature: 10–25°C (50–77°F)
Unopened rolls have longer shelf lives than partially used ones. Once a roll is exposed to air, dust and moisture can infiltrate the edges, accelerating adhesive degradation. Improper storage—such as stacking heavy items on rolls or leaving them in fluctuating temperatures—further compresses the film, causing the adhesive to transfer between layers.
To maximize shelf life, store rolls vertically in sealed containers, maintain proper temperatures, and avoid contact with oils or chemicals. Regular checks for signs of aging—like cracked edges or uneven adhesion—help ensure the film performs as intended when used within its shelf life.
