PLA Biodegradable Film is a biodegradable film made from plant-based materials. It has many benefits, including being resource-efficient, compostable, and having a low environmental impact. This video will show you how PLA is made and some of the benefits it has.
PLA Biodegradable Film Production Process
The PLA film production process is a three-stage process.
First, the raw materials are mixed in a large tank and heated to between 190 and 230 degrees Celsius (385 to 450 degrees Fahrenheit).
The second stage involves cooling and pelletizing. The mixture is cooled to between 30 and 40 degrees Celsius (86 to 104 degrees Fahrenheit) to form pellets. These pellets are then pressed into sheets that can be cut into any shape desired.
The third stage involves converting the pellets into a film by injection molding.
PLA biodegradable films can be used as packaging materials for food products, medical supplies, cosmetics and clothing items.
polylactic acid film Properties
The following are the characteristics of PLA Biodegradable Film:
-Printing Surface: Flat and glossy surfaces can be printed on both sides.
-Tensile Strength: Approx. 3MPa (30kgf/cm2), about 1.3 times PET/PP film, 1.5 times PE film.
-Compressive Strength: Approx. 0.8MPa (8kgf/cm2), same as ordinary HDPE sheeting. But less than that of ordinary PVC sheeting;
-Temperature Resistance: -40 ~ 100℃, suitable for high temperature environments;
-Heat Resistance: 80℃ without deformation or distortion;
-Light Transmittance: 85% or above;
PLA Film Applications
PLA Biodegradable Film can be used to make a variety of products, including:
The following are the most common applications of PLA films:
Packaging materials. These include shrink film, plastic bags and labels.
Food packaging. Some food companies use PLA packaging because it is compostable, biodegradable and recyclable. Also, The material is transparent and flexible so that it can be molded into different shapes for different food items.
Medical supplies and devices. PLA is often used in medical devices such as surgical instruments, catheters and syringes , because it does not contain chemicals that could cause allergic reactions or other problems in patients with compromised immune systems.
Building materials, including insulation panels and decking boards made of recycled plastics that can be used as composite materials in construction projects
PLA Film Environmental Performance
PLA Biodegradable Film is a biodegradable, plant-based polymer developed as a sustainable alternative to traditional plastics. The film is made from plant-based material and can be produced using various methods, including extrusion, casting, and injection molding.
polylactic acid film has several environmental benefits over traditional plastic films. Firstly, PLA does not contain chemicals or toxins that can harm the environment or human health. Secondly, PLA is compostable, meaning it can be broken down into organic material by bacteria in the soil. This property makes PLA an attractive option for disposable items such as food packaging or beverage containers.
Despite these benefits, some limitations exist when using PLA film. Firstly, the film is not flexible enough to be used in applications that require flexibility, such as eyeglasses or medical devices. Secondly, the film may not withstand extreme temperatures well; it should be stored at room temperature to prevent damage.
Conclusion
To sum up, biodegradable plastics and how they degrade have to do with the type of monomer and oligomer compounds used in the production process. PLA Biodegradable Film has a different composition than PET, which makes it easier for bacteria to attack the polymer chains to break them down. The longer it takes a disposable plastic product to break down, the greater likelihood that it will clog landfills.
