FLEXcon has announced the launch of optiFLEX RESEAL BARRIER Clear, a new PVDC-coated film that serves as a barrier against moisture to maintain food freshness and the moistness of wet wipe products. The product was developed for resealable packaging to retain moisture and prevent drying of produce, meats, cheeses and wet wipes, or to keep moisture out to prevent staling of nuts and other snack foods.

The polypropylene leveraged in this product offers tear resistance and durability for repeated opening and reclosure of flexible packaging substrates, and the film conformability provides label and graphic coverage. Further, the film clarity is designed for achieving the no-label-look on printed flexible packaging material.

“As the use of resealable packaging continues to increase, there is a growing need in the food market for packaging materials that enhance shelf life by maintaining food freshness,” says Michelle Lamontagne, market development specialist, product identification, FLEXcon. “The barrier properties of the PVDC-coated polypropylene provide moisture control ideal for these purposes, and this product serves as an example of our continued effort to meet the unique needs of the food packaging market.”

The film complies with 21 CFR 175.320 and 21 CFR 177.1520 for food contact, and the adhesive complies with 21 CFR 175.105 for indirect food contact. The resealable pressure-sensitive acrylic adhesive bonds well to low- and high-surface energy laminated flexible packaging substrates with clean, quiet and consistent reclosure, and the adhesive displays clarity and wet out characteristics.

The optiFLEX RESEAL BARRIER Clear utilizes a 2 mil clear PVDC-coated flexible BOPP film with a resealable adhesive and TRACrite™ 120 polyester release liner, which offers on-press performance for tight-registration graphics. The print-receptive surface of the film is also compatible with flexo, rotary screen, rotary letterpress and hot stamping, and its surface smoothness is intended for optimum ink laydown.
