Food Manufacturer Saves 37% on Poly Carton Liners

Encore Poly has been supplying a leading food manufacturer with three different size poly carton liner bags for over 12 years. After performing many tests, it was determined that we could convert two of the bags to our proprietary polyethylene blend and save this customer a considerable amount of money.

Over a one year period, this customer saved 37% on one size and 35% on the other. The conversion to this proprietary blend has worked extremely well for this customer who uses the bags as a carton liner in a freezer application. Read more

Custom Bags for the Cosmetic Industry

Case Study

Encore Poly was requested to provide a major chemical company that manufactures powders for the cosmetic industry with a flexible polyethylene bag that would not create static as their product is highly flammable. Between our R & D team and the help of our suppliers we found out that an amine and nitro free bag needed to be produced. In addition to this we needed to provide a “non-blooming” anti-stat. Most anti-stats have a tendency to “bloom” to the surface which this customer said was not acceptable. After months of testing different blends of resins and anti-stats we were successful in meeting all their requirements. Read more

What is polyethylene resin?

Polyethylene

There are many types of resin. For the plastic packaging industry, polyethylene resin is commonly used. It is a type of thermoplastic used to manufacture bags, tubing, sheeting, stretch and shrink films. It is also a flexible composite. Polyethylene, referred to as PE, is usually a mixture of polymers and ethylene. It has mechanical, thermal, chemical, electrical, and optical properties. It absorbs almost no water, burns slowly and cannot be imprinted without pretreatment. PE can become brittle when exposed to sunlight. To avoid this a UV stabilizer must be added.
