EVAL™ offers advantages in recycling: adding 10 percent PP-EVOH recycling material from industrial sources to recycled PCR-PP or PCR-HDPE from domestic refuse collections does not affect food-safe cleaning, further processing or physical properties compared to PCR-PP or PCR-HDPE alone.
Variation in recycling programs, unclear labeling, and inaccurate recyclability claims make proper recycling a challenge. The How2Recycle label was created to provide consistent and transparent on-package recycling information to consumers in North America.
Coex tubes. Layer 1. LDPE (low density poly ethylene ) Layer 2. Bonding agent = Double-sided adhesive Layer 3. EVOH barrier Layer 4. Bonding agent = Double-sided adhesive Layer 5.

EVOH is an Ethylene-Vinyl Alcohol Copolymer mainly composed of carbon, oxygen and hydrogen. It has no toxic gases when burned, and its combustion heat is only half that of polyethylene, causing little harm to the environment.
By recycling your used oil you not only help keep our water supply clean, but help reduce American dependence on foreign oil. It takes 42 gallons of crude oil, but only one gallon of used oil, to produce 2.5 quarts of new motor oil. Many garages and auto-supply stores that …
How to Recycle PP/PE Plastic Film . Applications of plastic film. Plastic film is widely used in our daily life, such as preservative film, plastic farm film, food package, medicine package. They are bringing us great convenience and are in great demand every day.
Jun 22, 2016· United States – Dow Chemical has found a solution for recycling certain types of multi-layer plastic pouch that would otherwise be thrown away. The US company's so-called RecycleReady technology works for one particular pouch design and is expected to form the basis for a …
EVOH is a common layer material used to increase the barrier properties of PP. It is not separable in the recycling process and therefore will become part of the recycled PP. Although EVOH blended with PP is not without issue (it may cause splay when extruded or molded and contribute to die lip build up) it is generally accepted.
EVOH films are also difficult to recycle because the EVOH oxygen barrier layer sandwiched between two or more PE layers has a tendency to gum up when reprocessed, resulting in holes in the recycled PE film. On the upside, EVOH waste does not produce toxic or harmful by-products when properly incinerated.
Jun 17, 2016· Dow originally developed Retain to help post-industrial recyclers reuse their PE and EVOH film, dosing it in with scrap material to allow EVOH to become compatible with PE during recycling.
Going back a number of years ago, co-injection/stretch blow-molded PET bottles were a major technology used for high oxygen barrier, typically incorporating EVOH. Over the years there has been a trend away from co-injection/stretch blow-molded barrier bottles to other technologies.

EVOH is a common layer material used to increase the barrier properties of HDPE. It is not separable in the recycling process and therefore will become part of the recycled HDPE. Although EVOH blended with HDPE is not without issue (it may cause splay when extruded or molded and contribute to die lip build up) it is generally accepted.
Jun 22, 2016· Until now, this combination of PE and EVOH has presented a problem to recyclers because the barrier layer sandwiched between PE layers essentially gummed up when reprocessed, resulting in holes developing in the recycled PE film. According to Stacy Fields, director of packaging solutions at Dow Chemical, the new approach is revolutionary. .
Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde, the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.
Why EVOH. PREMIUMPACK cares about reducing environmental impact through the use of EVOH resins. EVOH is an Ethylene-Vinyl Alcohol Copolymer mainly composed of carbon, oxygen and hydrogen. It has no toxic gases when burned, and its combustion heat is only half that of polyethylene, causing little harm to the environment.
pp-evoh-pe Even when contaminated, the material has good sealing properties, and can be sealed with a wide range of common sealing films from various manufacturers. Thanks to the material's high barrier, temperature and sealing properties, the trays are also ideal for the skin packaging of all meat types and seafood where a longer shelf-life is desired than can be achieved with MAP packaging.
