Thermoform modified atmosphere packaging machines for Sandwich
Sandwiches are much favored in our daily life. Containing sliced bread, vegetables, meat, cheese, egg, sandwich are often considered fast food.
To ensure the max freshness, the sandwiches are generally delivered directly to the stores after being produced by the factory on the same day. This form limits the development of manufacturers and the expansion of sales scope. Thus, the thermoforming modified atmosphere packaging machines emerge.
Different from traditional paper packing, film wrapping, or prefabricated cased, the thermoform modified atmosphere packaging machines apply an innovative method. Firstly, the package is formed after the plastic film softens by high heat. Then the sandwiches are filled into the thermoformed cups. After that, we vacuum, gas flush protective gases then seal the cups. The individual pack of the sandwich is ready after die-cutting.
The customers can choose different packaging materials for different sandwiches. For sandwiches that taste better after heating, PP material is more recommended.
For sandwiches stored at chilling temperature, PET is a good choice as consumers can see the sandwich condition clearly through the transparent boxes. MAP, modified atmosphere acts as a protective cost around the sandwich after the air is removed. Most bacterial can’t survive in the absence of oxygen, so the shelf life of the sandwich is extended.
The new MAP packing method can greatly increase efficiency and reduce package costs for many companies. As it’s helpful to reduce packing film, avoid the second pollution of ready boxes, the food shelf life can be tripled maximally. In this way, the sandwich market scope can be expanded.
