Certain types of food require semi-rigid packaging. Thermoforming is a manufacturing process in which a sheet of plastic is heated to a temperature at which the product becomes pliable, molded into a specific shape in a mold, and then trimmed to make a usable product.
When referring to thinner thicknesses and certain types of materials, the sheet or “film” is heated in an oven to a high enough temperature that it can be stretched in or on a mold and cooled to its final shape.
The materials used for thermoforming packaging are mainly PVC, PET, PP and PS.
Different options are available:
–Heat sealable –
peelable material
– Color film
– high barrier material
– Available thicknesses between 100 and 800 microns.
APG can supply semi-rigid packaging materials to meet your specific needs.
