What Is PHA Coating?

PHA (Polyhydroxyalkanoate) is a biodegradable polyester produced by bacterial fermentation of renewable feedstocks.

What Is Water-Based Barrier Coating?

Water-based barrier coating is a PFAS-free technology that uses aqueous dispersions of polymers to create a protective layer on paper and paperboard.

Requesting barrier paper samples is most useful when the supplier understands your real food, package format, converting process and target market. A clear sample request helps avoid testing the wrong grade and shortens the path from material screening to production trial.

Compostable barrier paper and recyclable barrier paper are both used to replace conventional plastic-coated packaging, but they are not interchangeable.

Bakery packaging needs more than a nice paper feel. Croissants, cakes, pastries, cookies, bread, muffins and butter-rich foods can expose packaging to oil, moisture, heat, sugar and release requirements.

PHA coating is a functional coating used on paper to improve barrier performance while supporting bio-based or compostability-oriented packaging strategies.

Water-based coating is a functional coating applied to paper or paperboard to improve resistance to oil, water, moisture or heat-sealing conditions.

Food contact paper is not selected only by barrier performance. Buyers also need a clear compliance file that matches the market, food type, contact conditions and converting process.

Greaseproof paper and barrier paper are often compared in food packaging projects, but they solve different problems. Greaseproof paper is mainly selected to control oil and fat migration.

How to Choose Heat-Sealable Barrier Paper for Food Packaging

Heat-sealable barrier paper is used when a package needs paper-based structure plus a sealable barrier layer.

Choosing Barrier Paper for Burger Wrappers and Fast Food Packaging

Burger wrappers, sandwich wraps, fry liners, and fast food wrapping papers need strong grease resistance, good folding behavior, printability, food-contact safety, and a clean customer experience.

Choosing Barrier Paper for Lunch Boxes and Takeout Containers

Lunch boxes and takeout food containers need more than a basic paperboard structure.
