Biodegradable, Environmentally Friendly Acetate Film & Sheet
When choosing a Biodegradable Plastic Material, its important to understand the types of biodegradable plastic film technologies and how those products are rated. There are three main types of technologies and all are evaluated by both Government Agencies and well as Non-Governmental Standards Organizations.
Bellow is an outline of the major biodegradable plastics technologies and how they are used.
Types of Biodegradable Technologies:
- Bio/Organic-based Plastics: This type of technology utilizes organic materials to manufacture the resin or feedstocks used to make plastic. In the case of Grafix’ Biodegradable Acetate, we use wood pulp from responsibly managed North American Forests. Other plastic materials in this category use food-stuffs such as Corn, Soy Beans, and Potatoes to produce Polylactic Acid (PLA) to make plastic.
- Photo-degradable Plastics: This type of technology allows the plastic material to breakdown in sunlight. Used in Agricultural application, this type of film is deployed in the growing field and starts to breakdown throughout the growing season. However, with some of these materials, once the material is taken out of the sunlight it might not continue its breakdown process.
- Thermal-degradable Plastics: This material is manufactured by taking existing petroleum based resin and adding formulated additive. When this material is buried in a landfill, or composted, exposure to the elevated temperature causes this material to be broken down by the bacteria in the ground. However, to date, with this type of technology the film might not break down completely, and risks leaving chips of non-degradable material behind.
