We all want to keep our food and drinks safe and free of harmful toxins and chemicals. The plastic containers and bags we use to store our consumables sometimes release these toxins and harmful chemicals. However, not all plastic bags are unsafe.
1, High-Density Polyethylene Bags 
HDPE has qualities that make it become one of the most commonly used plastics in the world, an excellent material for plastic bags.
HDPE is lightweight, resistant to temperature, water, and vapors, has high tensile strength, is relatively transparent, and meets FDA/USDA food handling guidelines, making great multipurpose bags for both serving and storing food in retail and takeout situations.
HDPE food storage bags will allow your grocery store, convenience store, fast food store or restaurant to operate at greater efficiency, no matter how you choose to use them.
2, Low-Density Polyethylene Bags
Similar to HDPE, LDPE meets FDA/USDA food handling guidelines. It is flexible, soft, transparent, glossy and highly resistant to moisture, tear and chemical resistance.LDPE bags are more transparent than HDPE, which is very suitable for making transparent ziplock sandwich bags. In addition, they can be used to store bulk food items such as fresh vegetables and fruits.
3, Linear Low-Density Polyethylene Bags
The biggest difference between LLDPE and LDPE plastic bags is that LLDPE food bags are thinner, but have the same strength though. Similar to LDPE bags, LLDPE bags meet FDA/USDA food handling guidelines, providing good barrier properties against moisture, gasses and odors, helping to keep food fresh for longer periods of time.
LLDPE’s flexibility is the highest of 3 kinds. In the food industry it is mainly used to package food products that need to be flexible or have a lot of movement in the packaging, for example frozen food, snack or food shrink film.
