Everyone has seen a thermoformed tray before, but you might not have given these items a second thought. However, these special trays are used in a variety of industries, such as for food packages, and they come in many shapes in sizes. For some trays, there needs to be just one single cavity while other trays might need to be constructed including several different cavities, each of which will be a specific size. These specific cavities can help protect food as well as other items.
Thermoforming is considered a manufacturing process whereby some manufacturers will heat plastic sheet at very high temperature making them soft and then they are shaped into any shape the manufacturer wants. Heated plastic can actually assume any form. Once the heated plastic is shaped, it is then cooled slowly hence retaining the formed shaped. The heated plastic mold makes it easy for molders to make beautiful containers of different shapes and contours.
This is how your plastic food packaging is created. Your thermoform tray packaging can carry a large amount of one type of food or perhaps house different foods in separate cavities. Frozen food containers typically are thermoform trays that can withstand the rigors of re-heating either in an oven or in the microwave. Additionally, a thermoform tray often will hold a food item such as dozens of crackers or perhaps cookies. Once placed in the tray a foil pack will cover these food items and they further will be protected by a box.
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.
