A thermoformable bottom web provides an economical option for filling and sealing packaging in the frozen foods markets, its manufacturer claims.
With the rise in costs for plastic packaging due the price increases for petroleum, the new material offers food processors another option on the market.
ClearForm is a proprietary copolymer blend from Rollprint Packaging Products that is tough, clear and has what the company calls an unusually wide thermoforming processing window.
Rollprint is offering the material as an alternative to traditional bottom webs such as EVA, Surlyn, nylon coextruded films, and other polyethylene-based polymeric blends.
ClearForm provides the same critical performance benefits at a reduced cost, the company claims. The product is suitable for ethylene oxide gas and gamma sterilization procedures used by the foodindustry.
When coupled with Rollprint's line of peelable top webs, the total package offers a smooth, peelable, tamper evident seal.
ClearForm is the first product to be launched by Alliantz Flexible Packaging, the newly-formed joint venture between Rollprint Packaging and Acme Packaging of Singapore.
The company says the polymer can also be used for sterile medical packaging.
