Supporting Circular Flexible Packaging

Fresh-Lock works closely with converters and brands to develop closure solutions that support evolving sustainability goals without compromising performance or production efficiency.

As packaging regulations, extended producer responsibility policies, and labeling requirements continue to evolve, many brands are evaluating new material structures and packaging formats.

This portfolio of sliders and zippers helps provide sustainable packaging to the marketplace with minimum reduction in production efficiency while still delivering the ideal consumer experience.
