Thermoformed plastic products are used in a wide range of applications including food packaging, pharmaceuticals and electronics. Food trays, yoghurt tubs, sandwich packs and blister packs are all thermoformed products, and we all use them every day, but how does thermoforming actually work?
The thermoforming process starts by heating a thermoplastic such as polystyrene, or polypropylene, to soften it. This heated plastic is then pulled over a mould of the desired shape and the trapped air is sucked out to form a tight fit over the mould. The article is then cut out and the resulting waste is recycled to be then re-extruded by Euro Extrusions, then thermoformed at a later date, after being granulated. Finished articles are often stacked at the end of the process to be shipped more efficiently.
The thermoforming process is very simple, allowing for high-volume, low-cost production of mass market packaging, which has become essential in the modern food market. Appearance is key in a lot of markets, and there are two main methods for introducing designs to thermoformed items. The first is pre-printing the design and applying it after the item has been formed. The second involves printing directly onto a thermoformed product, and is therefore limited by the final shape of the product.
