In the present world there is a vast amount of packaging needs, and for all that a ready available plastic carry bag is not enough. Type of plastic packing depends on the material to be packed. Plastic packing material used to pack dairy products will be different from the one that is used for packing fruits and vegetables. Each plastic packing bag should have its own special functions and abilities. By implementing custom packaging you can improve the quality of a product. When food products with low shelf-life are packed in one type of plastic container, edible products with long shelf-life is packed in other type of plastic boxes.
Plastic bags are made from the raw materials derived from the ethane gas. When compared to burning ethane as a waste product, converting ethane into plastic reduces the emission of greenhouse gases. This protects atmosphere, while assisting in packing different materials. In the wholesale food packaging world plastic bags and boxes are the champions.
Plastic food packaging bags are made of different kinds of plastic materials. Listed below are some of types of plastics used for food packaging.
Polyethylene Terephthalate or PET – This plastic material is tough and can prevent gas and moisture from leaking out. This property helps in using plastic bottles made with PET for storing water, fresh juices, salad dressing, and beer. Jars made with PET is used for storing jams, pickles, jellies and other food stuffs that have long shelf-life. Other than using for carry-out food packaging, PET is also used in making monofilaments, textiles, films and carpets.
High Density Polyethylene or HDPE – This plastic material is used in making different types of plastic bottles. HDPE bottles are good barriers of moisture and gas. Milk and milk products are packed in such bottles. Other than milk, the bottle can be used for juices, cosmetic creams, lotions, shampoos, detergents and other cleaning liquids. Bags or boxes made with HDPE can be used to store cereals and grains. In grocery shops, cereals and grains are available in HDPE boxes and bags. Many use HDPE for carry-out food packaging purposes. Other than these, the plastic material is used in strengthening wire and cable covering and moulding applications.
Custom plastic packing has a diverse role in protecting food products, preventing from decay, stopping contamination, improving shelf life and ensuring safe storage. Each type of food product should be packaged according to its biological and chemical properties. Plastic packaging is the most demanding type of packaging as it offers unique advantages over conventional packing materials.
Safety is the primary reason. Food stuffs packed in custom designed plastic containers especially polyolefin’s will not contaminate food or react with the food. The most important advantages of custom packed plastic containers are its low cost and convenience. Plastic can be converted to bags, covers, boxes or containers. We can carry it to different places and use it to store food materials in a convenient way.
