Henkel offers heat seal coatings and adhesives for food packaging lidding across foil, film, and other formats, helping converters, film producers and packaging manufacturers achieve dependable sealing, peelability, and resealability.
Lidding solutions include films, foils, heat seal coatings, and sealant structures used to securely close cups, trays, tubs, pods, and bottles. Depending on the application, they maintain seal integrity, protect product quality, improve visibility, and offer peelable or resealable convenience.
Selecting the right lidding solution depends on factors like substrate, container material, fill product, seal temperature, dwell time, performance needs, and regulatory requirements. Henkel partners with converters, film producers, and manufacturers to identify the best heat seal coating or adhesive via application testing and compatibility checks.

Lidding refers to the film, foil, coating, or seal structure used to close a food package such as a cup, tray, tub, pod, bottle, or container. Depending on the application, lidding can support seal integrity, product protection, peelability, resealability, product visibility, and performance under refrigerated or elevated-temperature conditions.
A heat seal coating is applied to a film or foil structure to enable sealing to a cup, tray, tub, or container under defined heat, pressure, and dwell-time conditions. Heat seal coatings help determine seal strength, opening characteristics, substrate compatibility, and packaging performance.
LOCTITE LIOFOL HS 1161 is designed for unit-portion food packaging applications and can be evaluated for dairy cups, coffee pods, condiment packaging, and dry food portion packs. It is suitable for both foil and film lidding structures and is documented for sealing to PP, HIPS, APET, and PVDC/HIPS cupstocks.
Yes. LOCTITE LIOFOL HS 1161 is documented as sealable to PP and other cupstocks. PP applications should always be evaluated under actual process conditions because sealing temperatures and dwell times may vary depending on the package structure.
