BOPLA High-Barrier Glossy Film – Keyful PLA-TBM
•Derived from renewable corn, certified for industrial composting.
•Outstanding printability: stable tension performance, compatible with flexographic, gravure, offset, screen, and UV printing, and perfectly supports hot stamping and other premium finishing processes, delivering a high-end look and feel.
•Excellent barrier properties: resistant to moisture, water, and oxidation, with fold resistance and high gloss.
•Functionality: Inherent anti-static properties and excellent resistance to oils and grease.
Oxygen barrier: 20; water barrier: 15.
Keyful PLA-TBM combines industrial compostability with high barrier and high gloss properties: Stable tension enhances printability of BOPLA glossy film, provides strong oxygen and moisture barrier performance, and offers antistatic and oil resistance, making it ideal for customized flexible food packaging.
Nos centramos en la investigación y el desarrollo, la producción, la fabricación y el suministro de diversos films de envasado flexibles, ecológicos y biodegradables, que abarcan BOPP, BOPET, BOPA, PE y films monomateriales reciclables, y nos comprometemos a satisfacer las diversas necesidades de soluciones de envasado del mercado.
Keyful BOPLA High-Barrier Glossy Film -PLA-TBM is based on industrial compostable PLA derived from renewable corn, possessing certified compostability. It exhibits a high-gloss appearance and a delicate feel, while a stable tension system enhances the printing adaptability of the BOPLA glossy film, compatible with flexographic, gravure, offset, screen printing, and UV printing.
It is also friendly to high-end post-processing such as hot stamping. In terms of performance, it features a low oxygen transmission rate (down to 20), excellent wetting/moisture and oxidation barrier properties, and inherent antistatic properties with good resistance to oils. It is suitable for brand packaging seeking consistent quality and supply chain compliance.
Aplicaciones
Flexible Packaging Industry: Used as an intermediate barrier layer, a surface printing layer, or a heat-sealable layer in tea bags, coffee packaging, and food packaging.
Flexible Packaging Converters: Can be used as a heat-seal layer/laminate layer in multilayer structure designs, reducing moisture regain and improving the after-opening appearance of finished products.
Tea & Coffee Brand Customizers: Used for high-gloss surface presentation and fine printing effects, combined with hot stamping/advanced processing to enhance shelf appeal and brand texture.
Sustainable Packaging Supply Chain Providers: For customers requiring industrial compost certification, serves as a Compostable glossy BOPLA film structural material to support green compliance and differentiated promotion.
