Eco-Friendly Biodegradable Film: Sustainable Solutions for Diverse Applications
YITO's biodegradable films are mainly divided into three types: PLA (Polylactic Acid) films, cellulose films, and BOPLA (Biaxially Oriented Polylactic Acid) films. PLA films are made from renewable resources like corn and sugarcane through fermentation and polymerization. Cellulose films are extracted from natural cellulose materials such as wood and cotton linters. BOPLA films are a advanced form of PLA films, produced by stretching PLA films in both machine and transverse directions. These three types of films all have excellent biocompatibility and biodegradability, making them ideal substitutes for traditional plastic films.Product Features
-
Exceptional Environmental Performance: All three films can be completely decomposed into carbon dioxide and water by microorganisms in natural environments without leaving harmful residues, meeting environmental protection requirements. Their manufacturing process is also more energy-saving compared to traditional plastics, resulting in lower carbon emissions and minimal environmental impact.
-
Good Physical Properties: PLA films have good flexibility and strength, capable of withstanding certain tension and bending forces without breaking easily. Cellulose films have better breathability and moisture absorption, which can effectively regulate the humidity inside the packaging and extend the shelf life of products like food. BOPLA films, thanks to the biaxial stretching process, have significantly improved mechanical properties, including higher tensile strength and better impact resistance compared to ordinary PLA films.
-
Stable Chemical Properties: Under normal use conditions, all three films can maintain stable chemical properties, avoiding reactions with the contents of the packaging and ensuring product safety.
-
Excellent Printability: These biodegrradable films support various printing methods, including direct and reverse printing, enabling high-precision pattern and brand logo printing to meet different customers' personalized needs.
Limitations
- PLA Films: The thermal stability of PLA films is relatively average. They have a glass transition temperature of around 60°C and start to decompose gradually at around 150°C. When heated above these temperatures, their physical properties change, such as softening, deforming, or decomposing, limiting their application in high-temperature environments.
- Cellulose Films: Cellulose films have relatively lower mechanical strength and tend to absorb water and become soft in humid environments, affecting their performance. Additionally, their poor water resistance makes them unsuitable for packaging scenarios requiring long-term waterproofing.
- BOPLA Films: Although BOPLA films have improved mechanical properties, their thermal stability is still limited by the inherent properties of PLA. They may still undergo slight dimensional changes at temperatures close to their glass transition temperature. Moreover, the production process of BOPLA films is more complex and costly compared to ordinary PLA films.
Application Scenarios
-
Food Packaging: Made into cling film, they are suitable for packaging various foods like fruits, vegetables, and baked goods. The high barrier properties of PLA films and the breathability of cellulose films can both maintain the freshness and taste of food and extend its shelf life. Their biodegradability also solves the environmental pollution problem of traditional plastic packaging in food waste disposal.
-
Product Labeling: Provides eco-friendly labeling solutions for various products, ensuring clear information display while reducing environmental burdens.
-
Logistics and Transportation: Used as strength film, they can wrap items in the logistics industry, protecting products during transportation. Their mechanical properties ensure package integrity, and their biodegradability reduces the environmental impact of logistics waste.
-
Agricultural Covering: Used as soil cover films in agriculture. The breathability and moisture absorption of cellulose films help regulate soil humidity and temperature, promoting crop growth, and can be naturally degraded after use without the need for recovery, simplifying farming operations. Therefore, they can be used as mulch film to protect crops.
- High-end Product Packaging: BOPLA films, with their excellent mechanical properties and optical properties, are suitable for packaging high-end products such as cosmetics and electronic products, providing good protection and an attractive appearance. Cellulose films can be made into differernt types of packaging bags, like cigar cellophane sleeves, cellulose lap seal bag.
