PLA Stretch High strength Film -Keyful PLA-STF

  • Derived from renewable corn, certified for industrial composting.
  • Translucent
  • High strength, good toughness, excellent puncture resistance
  • Alternative to PE stretch film

Keyful PLA-STF, based on industrially compostable PLA, offers a translucent appearance and excellent puncture/tear resistance while maintaining high strength and toughness. It balances efficiency and environmental compliance in pallet wrapping and transportation protection, making it a more competitive alternative to traditional PE stretch film.

Nous nous concentrons sur la recherche et le développement, la production, la fabrication et la fourniture de divers films d'emballage flexibles, respectueux de l'environnement et biodégradables, y compris les films BOPP, BOPET, BOPA, PE et les films mono-matériaux recyclables, et nous nous engageons à répondre aux divers besoins du marché en matière de solutions d'emballage.

Keyful PLA-STF PLA stretch film is made from renewable corn-derived materials and is industrially compostable certified. As a biodegradable/compostable PLA stretch film, it offers an eco-friendly PLA stretch film alternative for green packaging. The film is translucent and boasts both high strength and toughness. It exhibits excellent performance in both MD/TD directions, with superior puncture resistance and good tear resistance, making it suitable for finished product packaging protection applications that require impact resistance and reduced risk of damage.

Applications

  • Suitable for packaging across various industries, compatible with both machine and manual use.
  • Suitable for basic protective packaging of out-of-pallet parcels, bundling, and dust/moisture prevention, reducing friction and wear during transportation.
  • Tailored to wholesale customization users, adapting to different stretching ratios and process cycle time requirements, improving wrapping efficiency and stability.
  • Tailored to wholesale customization users, adapting to different stretching ratios and process cycle time requirements, improving wrapping efficiency and stability.

    Made from renewable resources like corn and certified for industrial composting, it aligns with the intended use of compostable PLA stretch film.

    It boasts high strength and good toughness, especially higher TD strength, while also demonstrating excellent puncture and tear resistance.

    The appearance is Translucent, providing a certain degree of matte finish and obscuring effect; if complete opacity is required, the process and thickness can be further evaluated.

    Both are suitable. The film material is compatible with common machine and manual wrapping methods, facilitating factory upgrades and multi-station operations.

    Although it is an ultra-thin specification, high strength and high toughness are achieved through formulation and structure. The elongation at break is outstanding, and the puncture and tear resistance are more suitable for transport fixation.

    The film emphasizes toughness and puncture resistance, which can help reduce the risk of damage caused by external forces and improve pallet wrapping stability.

    The MD direction is more biased towards toughness and elongation, while the TD direction has higher strength; in actual wrapping, a more stable wrapping effect can usually be obtained by matching tension and orientation.

    We can collaborate on the design of film specifications, width, usage, and packaging process parameters to facilitate project implementation for PLA stretch film suppliers / manufacturers.
