Thermoform trays generally can include things like one compartment to flat tray manufactured basically for holding merchandise and also complex cavity designs produced according to specification such as contours and shapes simply for protecting, holding and safeguarding fragile, precious and expensive items. Some designs of thermoformed trays are usually used for food packaging.
These trays are fashioned using a process known as thermoforming, which is why we call them thermoformed trays. During this process, think sheets of plastics are heated to a temperature that will make the plastic very pliable. From there, a thermoforming machine will shape the plastic into trays, cool the plastic and trim away the excess plastic. These special plastics can be molded into virtually any design, including very complicated thermoform trays.
Food packaging containers are also formed this way. The container can carry significant amount of food hence making it very ideal for carrying food. You might see these thermoformed trays used for frozen food containers, for food storage containers and for items such as cookies and crackers. These latter items will be placed in a tray and then often placed inside a plastic or foil bag or perhaps a box for further protection.
While food products might be seen commonly in thermoform trays, other types of companies also need these trays. If you have ever noticed, you might remember that a doctor or nurse will use a medical kit where items are stored in thermoformed tray. One cavity might hold a syringe, while another cavity might hold medicines or other medical instruments. You also might buy retail products, where components are stored in a thermoform tray, resting is a perfectly designed cavity that protects each part of the product. To form a tray, different types of thermoplastic can be considered for use and these include LDPE, HDPE, OPS and commonly PVC or PET.
PVC is the generally the common material used when forming web. The material has several benefits which include, they are less expensive to acquire and transport because they are of light weight. PVC is materials known to be quite easy to mold. The durability of PVC makes it very ideal. There some disadvantages associated with it too.
Another very common thermoplastic is polyethylene terephthalate, which is known by the easier to remember moniker of PET. This is an easy-to-recycle thermoplastic typically used for holding beverages and other liquids, containers, trays and even as synthetic fibers. One of the key benefits of PET is that it acts as an excellent barrier for many liquids. Sometimes PET also will be sandwiched with a polyvinyl alcohol and this reduces the PET's oxygen permeability. At any rate, PVC and PET are just two of the choices to consider for thermoformed trays.
