Expanded polypropylene (EPP), very similar to EPS, it is also obtained from rigid polymer beads heat expansion, resulting in closed cell foam which is flexible, lightweight and heat/cold resistant, an environmentally-friendly product. It has a better shape memory, giving it greater resilience and allowing it to deform without breaking. 100 % recyclable.
Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. With its features of transparency and high-food grade quality raw material, Polypropylene is one of the most versatile polymers available of the plastics in food packaging markets. PP is cost-effective, disposable, safe, versatile and environmentally friendly and is ideal for food packaging.
Polystyrene is a rigid clear thermoplastic polymer that can be molded into objects or made into foam. Polystyrene food service packaging has many benefits. It is extremely strong yet lightweight and provides excellent insulation. It also keeps food fresher longer, and costs less than paperboard options. Polystyrene also has less environmental impact during its manufacture since it weighs between two to five times less than comparable paper packaging products, and requires about 50 percent less energy to produce than comparable paperboard packaging.

Polyethylene terephthalate (PET or PETE), polycarbonate, and polyethylene naphthalate (PEN) are polyesters, which are condensation polymers formed from ester monomers that result from the reaction between carboxylic acid and alcohol. The most commonly used polyester in food packaging is PETE. PETE provides a good barrier to gases (oxygen and carbon dioxide) and moisture. It also has good resistance to heat, mineral oils, solvents, and acids, but not to bases. Consequently, PETE is becoming the packaging material of choice for many food products, particularly beverages and mineral waters. The three major packaging applications of PETE are containers (bottles, jars, and tubs), semi rigid sheets for thermoforming (trays and blisters), and thin-oriented films (bags and snack food wrappers).

Polylactic acid (PLA) is a corn-based polymer and is compostable. (Bread bags, coffee/ window bags, bio-view sandwich bags) This environmentally friendly renewable resource is efficient to manufacture. Normal heat tolerance of PLA is 110 degrees (F). Remember to keep these products out of direct sunlight and place them in a cool, dry place.
Plain paper is not used to protect foods for long periods of time because it has poor barrier properties and is not heat sealable. When used as primary packaging (that is, in contact with food), paper is almost always treated, coated, laminated, or impregnated with materials such as waxes, resins, or lacquers to improve functional and protective properties.

Paperboard is thicker than paper with a higher weight per unit area and often made in multiple layers. It is commonly used to make containers for shipping—such as boxes, cartons, and trays—and seldom used for direct food contact. The types of paperboard packaging for food are white board, solid board, chip board and fiber board.
In general starch-based biodegradable plastics have starch contents ranging from 10% to greater than 90%. Starch based polymers can be based on crops such as corn (maize), wheat or potatoes. Starch content needs to exceed 60% before significant material breakdown occurs. As the starch content is increased, the polymer composites become more biodegradable and leave fewer residues. Our starch-based biodegradable food containers degrade safely and completely back into nature without releasing any toxic by-products. Our biodegradable clamshell, plates, cutlery, etc. have high heat tolerance of up to at least 190 degrees F in microwave oven. See our Starch-based biodegradable containers.
Biodegradable and Compostable
Biodegradable products break down by natural processes into smaller simpler parts that eventually decompose. Biodegradation can occur with the help of water, oxygen or light. On the other hand, compostable products decompose in a compost site with the help of microbes that can digest the material in a short amount of time, usually 60 to 180 days in industrial composting facilities.
Thermoformed and thermoglued wooden trays pack your product inside natural packaging. Our wood products are made from poplar trees. Poplar wood is approved for contact with all food types. It easily handles peeling, drying, gluing and surfacing, making it suitable for food packaging applications. The wood accepts various printing techniques, such as typography, pad printing, pyrography and wood dye. The wood also can be laminated with greaseproof paper or plastic film (PE, PP, PET). Many of our wooden trays can be used for cooking purposes, in either the oven or microwave.
