Markets We Serve
Sonoco specializes in rollstock lidding for various end-use applications, specially formulated to meet varying barrier levels, filling methods, product and print requirements. We have films that can seal through contamination, as well as withstand different processing methods, including HPP.
As more consumers are demanding transparency, more clear PET containers are being used to package fresh food products. Our lidding films are used to seal to PET trays for fresh and value-added fruits and vegetables.
Our lidding films are also used in the deli, dairy, and bakery segments for ready-to-eat soups and salads as well as protein multi-compartment snack trays.
SealChoice™ Peelable Lidding Films
Our SealChoice family of peelable lidding films is designed to seal directly to a variety of substrates, including polyester containers. We offer lidding films in both polymer and heat seal coating sealant layers to meet your needs.
We also offer a lidding that is compatible with high-pressure processing (HPP) typically used in guacamoles, salsas and meats. We maintain a hermetic seal during processing and offer a clean easy peel for the consumer.
Foil and Metallized Lidding
Our printed foil and metallized lidding is typically used to seal to HIPS or other substrates in the quick-serve restaurant industry for dips, dressings, and sauces. Our lidding is also used to package am and jellies as well as honey. This lidding can withstand the most demanding and hard-to-hold applications. Our lidding film is used in both FFS applications and in combinations with pre-made cupstock.
Sonoco also produces peel/reseal lidding films using both our proprietary SmartSeal® technology and our discreet label technology to suit varying needs. This could be a viable alternative to a rigid lid, while providing the consumer the convenience of recloseability.
