Extending fresh foods’ shelf life at room temperatures

Share

TAIWAN – One Taiwanese company has developed a vacuum-pack solution can allows fresh foods to be stored at room temperature while extending their shelf life.

These days, flexible plastic bags and pouches are often used to pack a variety of food products. While these flexible packaging options do offer protection to the products packed, fresh food items such as seafood, meats, fruits and vegetables still have to be stored in refrigerators. Not only does this take up refrigeration space, the packages effectively end up having to use additional energy in order to fulfil their function of product protection.

Wapo Corporation’s new nylon vacuum-pack bags offer an unconventional solution: the ability to store fresh foods at room temperature. 

Produced using plastic materials from Japan’s Unitika Ltd, Wapo’s vacuum-pack bags have good gas barrier properties that allow for moderate oxygen transpiration so the fresh food products are not attacked by caustic gases or exposed to premature oxidation.

When vacuum-sealed, the bags are puncture resistant, water resistant and vapour resistant. By reducing moisture loss, the bags extend product freshness in addition to shelf life.

And even if the vacuum bags are stored in sub-zero temperatures, the packaging material does not become brittle nor do the bags burst from expansion after freezing.
