PLA Heat Shrink Film-Keyful PLA-SHF

•Derived from renewable corn, certified for industrial composting.

•Translucent, high strength, good toughness, excellent puncture resistance, shrinkable and heat-sealable

•Suitable for various fully automatic packaging machines

•Alternative to POF shrink film

Keyful PLA-SHF combines industrial compostability with a high-clarity appearance. The film boasts high strength, toughness, and puncture resistance, while also delivering stable shrinkage and heat-sealing performance, making it suitable for fully automated packaging lines. It readily supports wholesale customization, enabling improved snug protection and enhanced visual presentation, while gradually replacing traditional POF solutions and alleviating compliance and image concerns.

We focus on the research & development, production, manufacturing, and supply of various flexible, environmentally friendly, and biodegradable packaging films, covering BOPP, BOPET, BOPA, PE, and recyclable single-material films, and are committed to meeting the diverse packaging solution needs of the market.

Keyful PLA-SHF PLA heat shrink film is made from renewable corn-sourced materials and has obtained industrial compost certifications, making it a green alternative in the realm of compostable PLA shrink film and biodegradable PLA heat shrink film. The film exhibits the high transparency appearance of Transparent PLA shrink film, while also possessing high strength, good toughness, and excellent puncture resistance. It also boasts shrinkable and heat-sealable properties, making it compatible with fully automatic packaging lines and suitable for heat shrink packaging, bottle labels, sleeve films, and other applications requiring high shrinkage rates. It can be customized as an alternative to POF shrink film.

Applications

  • Suitable for packaging products requiring shrink film, such as books, shoes, food, hardware, etc.
  • High-speed wrapping for product turnover packaging that requires enhanced protection and visual appeal.
  • Suitable for multi-SKU automatic stretch wrapping and shrink-wrapping applications, reducing changeover costs and downtime risks.
  • Packaging processes in customized projects that require specific light transmission, shrink range, and heat-seal stability.

    The raw material is derived from renewable corn and has been verified according to industrial composting certification systems, making it suitable for compostable PLA shrink film applications.

    With a transmittance of >85%, it aligns with the concept of ransparent PLA shrink film and is typically suitable for scenarios requiring clear display or visible packaging information.

    The shrinkage rate ranges from 40%-55%, which can satisfy the “tightness of wrapping” requirements of conventional shrink wrapping. The specific effect also depends on the heating method and material form.

    The product is specifically characterized as “Suitable for various fully automatic packaging machines,” facilitating mass production and stable production rates.

    It possesses shrinkable and heat-sealable capabilities, typically allowing for simultaneous shrinking and heat sealing through a heat source.

    The parameters include transverse/longitudinal tear strength and tensile strength, emphasizing overall high strength, toughness, and puncture resistance, making it suitable for logistics transportation and external force protection.

    With a melting point of approximately 120~160°C and a Vicat softening point A/50 of approximately 85°C, it is recommended to match the equipment temperature and speed during process development to ensure sufficient shrinkage and avoid excessive thermal stress.

    We can collaborate on designs focusing on thickness, target shrinkage effect, compatible machine models, and heat sealing process windows, providing process implementation support for wholesale customization projects.
