Food Packaging Materials

All of our food packaging products are manufactured in the ISO 9001 certified facilities. Many of the products are designed to package food items with the consideration of providing a long non-refrigerated shelf life.

Aluminum Foils for Processed Cheese

The foils for processed cheese are made with an FDA approved heatsealable lacquer especially designed to be compatible with modern packaging equipment. These foils can be used for individually packed portions or for large cheese circles. Whether used with the two foil process (shell and lid) or the single sheet process, the foils can provide a hermetic seal for a long shelf life. This foil is available in silver, gold and a wide variety of colors and shades. The foils can also be gravure printed with one to eight colors.

 

Retortable Foil Pouches for Shelf Stable Foods

Foil retort pouchesOur foil retort pouches are made in a 3 or 4 ply (OPA reinforced) structure to provide minimum packaging volume and maximum protection against light, oxygen, bacteria, viruses, and insects. These special structures can be used for flat and stand-up pouches. The pouches are designed for rigors of the retort process and are therefore suitable for a wide range of shelf stable, processed food products. We can supply preformed pouches for fill weight ranging from several ounces to 6 plus lbs. All of our retortable pouch materials which are made with a foil barrier are available as preformed pouches or in roll form for pouch production by the customer. The retort pouches can be supplied unprinted or up to 8 color printed and can be shaped to meet your special requirements. Material structure: PETP/AL/(PA)PP
 

Retortable Non-Foil Pouches for Shelf Stable Foods

Non-foil retortable pouchThese non-foil retortable pouches are made in a 3-ply reinforced structure to provide minimum packaging volume and maximum protection against light, oxygen, bacteria, viruses, and insects. Made with unique high barrier coatings, these retort pouches are clear yet provide the protection required for shelf stable processed foods and are suitable for heating in a microwave oven. The non-foil materials can be used for flat and stand-up retort pouches and are designed for your shelf stable processed food and processed food pouch products. They are suitable for fill weight ranges from several ounces to 6 plus lbs. The fully retortable materials (special retort grade high barrier materials are used) are available as preformed retort pouches or in roll form for pouch production by the customer. The retort pouches can be supplied as a fully transparent pouch or up to 8-color printed. Material structure: PETP/SiOx-PETP/(PA)PP or PETP/AlOx-PETP/(PA)PP.
 

Retortable Foils for Horizontal Form Fill Seal Pouch Machines

Retortable Foils for Horizontal Form Fill Seal Pouch MachinesRetortable pouch foils consist of a top (lid) and cold formable bottom (tray) material for production on horizontal form-fill-seal (HFFS) machines. The formability of these specialized provides all the advantages of the flexible retort pouch with the added advantages of automatic or manual horizontal filling of both placeables (sausages, muscle meat, etc.) and pumpable foodstuffs (stews, vegetables, etc.). With this system the range of pouching capabilities is greatly expanded by increasing the type of shelf stable and processed food items that can be easily placed in a pouch. HFFS pouches are suitable for fill weight ranges from several ounces to 8 lbs. The HFFS retort roll-stock can be supplied plain or up to 7 color printed. Material structure - top foil: PETP/AL/PP - bottom foil: OPP/AL/OPA/PP.
 

Retortable Foil and Non-Foil Lidding for High Barrier Trays

Retortable Foil and Non-Foil Lidding for High Barrier TraysThese foil based retort lidding structures are specially designed for sealing to high barrier PP trays. The trays can be shaped as bowls, cups or plates with typical applications for shelf stable soups, stews and prepared meals. Both a peelable and non-­peelable, version of the lidding are manufactured. The non-­peelable version requires a knife to cut open the lidding. Material structure - peelable: PETP/AL/PP coating – non-peelable: PETP/AL/PP.

These non-foil based retort lidding structures are manufactured with special retort grade high barrier SiOx or AlOx barrier films and are specially designed for sealing to high barrier PP trays. The trays can be formed in almost any shape such as bowls, cups or plates with typical applications for shelf stable fruit cups, soups, stews and prepared meals. Material structure - PETP/ SiOx (AlOx) PET/PP
 

Peelable Lidding for Metal and Composite Cans

Peelable Lidding for Metal and Composite CansThese lidding materials are available in a wide range of structures for many types of can applications.

Generally, our foil lidding is heatsealed to a tinplate or aluminum ring on membrane heatseal machines. These rings, with the easy peel end already sealed are then seamed to the top of tinplate or composite cans. Our lidding is always easy to open with the non-retort version designed for use with dry products (powdered milk, coffee, chocolate, cereals, nuts, etc.) and the retortable version designed for cooked products (fish, prepared meals, pet food, etc.). Material structure - non-retort lidding: Protective lacquer/AL/Heatseal lacquer or Paper/AL/Heatseal lacquer - retortable lidding: Protective lacquer/AL/PP coating.
 

Aluminum Container Stock for Cups or Trays

Alumiinum container stock for cups or traysThese special treated aluminum container foils are made specifically for formation into straight wall or wrinkled wall cups or trays suitable for hot fill or retort products. The container stock can be colored or silver and is treated with special high temperature protective lacquers and polypropylene sealant films. Once formed into cups or trays they can be sealed to high barrier polypropylene coated foil or non-foil lidding. The formed aluminum container stock can be used as cups or plates with typical applications for soups, stews, prepared meals or pet food trays and other applications that require high temperature performance.
