Film métallisé haute barrière BOPLA - Keyful PLA-BM
-Dérivé de maïs renouvelable, certifié pour le compostage industriel.
-Excellentes propriétés de barrière : résistance à l'humidité, à l'eau et à l'oxydation, résistance au pliage et haute brillance.
•Distinct functional features: anti-static properties and resistance to oil and grease.
•Oxygen barrier: 6; water barrier: 4.
BOPLA high-barrier metallized film is derived from renewable corn and certified for industrial composting, offering an eco-friendly alternative to conventional plastic films. It provides reliable moisture, oxygen, oil, and grease resistance, along with anti-static performance, fold durability, and high gloss. These features make it well suited for premium paper-plastic lamination such as gift boxes, handbags, and book covers, as well as barrier layers in tea, coffee, and food packaging.
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 BOPLA High-Barrier Metallized Film – PLA-BM is made from renewable corn-based materials and is certified for industrial compostability, combining environmental sustainability with premium performance. It offers excellent barrier properties, strong moisture resistance, and oxidation resistance, along with outstanding fold strength and a high-gloss surface. The metallized layer significantly enhances gas barrier performance, with an oxygen transmission rate of only 6 cc/m²·d and a water vapor transmission rate of 4 g/m²·d, making it ideal for packaging products that require strict freshness protection, such as tea, coffee, and various foods.
The film also features antistatic properties, oil and stain resistance, and a thickness of 15 ± 2 μm. With stable print compatibility, it supports flexographic, gravure, offset, screen, and UV printing, as well as hot-stamping and other premium finishing processes. This enables large-scale customized packaging with a high-end appearance and long-lasting freshness protection.
It is suitable for paper-plastic composite packaging, including gift boxes, color boxes, packaging bags, book covers, and outer cartons used in premium packaging applications.
Applications
Paper-Plastic Lamination: Premium gift boxes, color boxes, handbags, book covers, and outer packaging.
Flexible Packaging Industry: Used as an intermediate barrier layer in tea bags, coffee packaging, and food packaging.
Convenient Tea Bag / Coffee Packaging: Used as an intermediate barrier layer to extend aroma retention and freshness.
Dairy and Prepared Food Packaging: Provides long-term protection in applications requiring high oxygen barrier and low water vapor transmission.
