There can be many different types of thermoformed trays. In some instances, these might include just one single compartment often to hold just one item or perhaps to tote several items. In other cases, you will need to have a thermoform tray designed with several different, uniquely designed cavities to hold and protect several different items or parts. Often these thermoform trays are used to house food products.
The process of plastic thermoforming is the manufacturing method used to create thermoformed trays. This process begins by feeding huge sheets of thermoplastic into a machine. This machine will heat the plastic and when it reaches a certain temperature, the machine will use great force to direct the thermoplastic into specially designed molds. Once the plastic has been formed into a tray, it then should be cooled and any extra plastic will be trimmed from the thermoform tray and recycled.
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, also known as polyvinyl chloride, is a commonly used material for thermoforming. It is quite inexpensive and very lightweight, both of which are attractive to companies needed thermoform trays. Additionally, PVC is very easy to form and, once cooled, it is also quite durable. While there are a few disadvantages as well, PVC often is a popular packaging or thermoform tray plastic.
PET also called polyethylene terephthalate is a polymer resin thermoplastic used mostly in beverages, synthetic fibers, liquid containers, food container and thermoforming applications. PET is a good barrier material that is why many plastic bottles are basically made from it. For some particular bottles, this PET sandwiches some additional or extra polyvinyl alcohol hence reducing oxygen permeability.
