Eco Works® 70

Product Description

Eco Works® 70 Bio-Based, Biodegradable & Compostable products are specifically designed to replace non-degradable, oxo-biodegradable and other polyolefin-based products for a wide range of applications. Compared to HDPE, LDPE, and LLDPE products, Eco Works® 70 has improved strength while adhering to strict guidelines for commercial compostability as detailed in ASTM D 6400.

Eco Works 70 is heavily composed of corn-based resin resulting in flexible films ideally suited to pair with PLA-based rigid containers and products. Unlike “starch” containing bags, the corn-based polymer used in Eco Works 70 has strength, temperature, and moisture resistance equal to or greater than non-degradable polyethylene.

Eco Works® 70 is available in standard forms; semi-rigid sheeting, thin gauge flexible films, and bags. Versions of Eco Works 70 are also available for some shrink film, food contact, and pouching/lidding applications.

Eco Works® 70 masterbatch is also made available for select applications and is suitable for many molded, thermoformed, or laminated applications.

Technical Information

Eco Works 70 is a high-performance, unique blend of compostable polyesters. The majority of the composition is derived from a semi-rigid corn-based polyester. The improved rigidity over straight polyester or starch-polyester formulations allows unique properties including improved gloss, contact clarity, strength and tear/puncture resistance (both directions). Additionally, the rigidity from the corn-based polyester allows stand-up pouches, handle bags, drawtape closures, and several other unique functional attributes.

Under typical well run commercial compost conditions (microorganisms, turning, heat, moisture) Eco Works 70 products will be directly consumed by microorganisms and show visual change within several days. Complete conversion to carbon dioxide and water typically occurs within a few weeks.

Until the film is exposed to microorganisms, Eco Works 70 products will retain their original physical properties. Heat and moisture alone are not sufficient to cause 

Shelf Life

As described above, Eco Works 70 is a shelf stable product. Until the products are exposed to microorganisms or commercial composting conditions, they retain original physical properties and strength.

Food Contact 

The materials used in the production of Eco Works 70 are approved for many food contact applications. However, due to the unique and varied demands of food packaging regulations, please contact Cortec for more precise information on the suitability and approval of Eco Works 70 for food contact applications.
