A packaging tray is a strong, durable, low cost material used to protect food during transportation and storage. This type of packaging is often made of PET or PETG. It can be printed, registered, and bundled with film to provide added security during transport.
Packaging trays are typically designed to fit specific product or component part shapes. They may be used for general manufacturing, electronics, or health care applications. Some trays also contain desiccants to maintain controlled climates.
Many industries use trays to pack their products safely and efficiently. For example, the beverage industry uses trays to protect beverages from temperature and shock. The meat and seafood industries use trays to keep their products fresh, prevent bruising, and extend shelf life. And the snack industry uses trays to protect pre-packaged foods from moisture.
When looking for a packaging tray, it’s important to consider the size of the product, its weight, its shape, and its material requirements. The best tray for a given product is one that can support its own weight. Other factors include whether the package needs to be protected from oxygen, shock, or other environmental hazards.
Trays can be custom-made, but most are designed and manufactured by the manufacturer. Some of the most common materials used in this type of packaging are PET, PVC, and HIPS. However, there are other types of plastics that can be used for packaging, shipping, and material handling.
For the beverage industry, the most common style of tray is a 4-corner tray. This design allows for a retail-ready bottom and telescoping top. Additionally, the 4-corner tray is a great option for packing tissue products, as the telescoping lid helps to keep the package from bending.
Thermoforming is a great way to create custom plastic trays. Whether you need to ship a pallet of cakes or jarred goods, the versatility of a plastic tray is essential to a cost-effective packaging solution.

The principle and function of MAP TRAY:
MAP TRAY (Modified Atmosphere Packaging), just as its name implies, refers to the technology that artificially controls the proportion of gases (oxygen, carbon dioxide, nitrogen etc.) in the package to extend the shelf-life.
Our MAP trays are made from a high barrier, polypropylene material that can help extend shelf life. Hermetically sealed with barrier lidding film, the final output is a leak-proof package. This solid barrier tray/lidding film combination provides a self-contained BARRIER unit.
In a closed system, the proportion of ambient gases is modified to the condition which can reduce respiration and lessen the consumption of nutrients. To restrain cells’ respiration and retard the process of metabolism, however, make cells in a dormant state rather death. And whenever cells leave the modified atmosphere, they’ll still keep their normal pace of metabolism without other side effects. Of course, all these are on the premise of low temperature.
Different contents (meat/poultry/fruit) requires different in the proportion of ambient gases
Red Meat (beef, lamb,pork) — recommend high O2 condition (60–80% Oxygen and 20–40% Co2) high rate O2 to keep the meat red and percentage of Co2 to inhibit the growth of aerobic spoilage bacteria.
Poultry — recommend Co2 and N2 condition
Fresh-cut fruit — recommend low O2 and low Co2
