Biodegradable Polymer
Synthetic copolyesters derived from petroleum and bio-based monomers exhibit biodegradable and compostable properties while offering highly flexible film performance. Using polybutylene adipate terephthalate in packaging allows converters to produce strong, flexible films that will fully break down in composting environments. This polymer is frequently blended with polylactic acid or starch to balance the mechanical properties and improve the processing efficiency on standard extrusion equipment.
It replaces traditional polyethylene in retail bags, shipping bags, and agricultural films.
Physical Character
Material properties of this copolymer can be tailored to meet the specific requirements of the converting process. In the case of polybutylene adipate terephthalate, its high elasticity and puncture resistance make it ideal for thin-walled packaging films that must withstand handling and transit. Its low melting point allows it to be processed at lower temperatures than conventional plastics, which reduces energy consumption during manufacturing.
This flexibility also ensures that paper-based packaging coated with it remains compostable and heat-sealable.
Packaging Conversion
Converting factories laminate this material onto paperboard to create compostable moisture barriers for food packaging. This eliminates the need for non-biodegradable wax or polyethylene coatings. It enables the creation of fully certified home and industrial compostable barrier cups.
