The Most Common Food Safe Plastics by Plastic Sheet Suppliers

On most plastic products, you’ll find a number in a triangle. This number represents a grade that was set by the Food and Drug Administration. Only five grades are safe for consumable items.

Grade One – PET Plastic

PET stands for polyethylene terephthalate. It’s a lightweight, clear plastic with a strong core. Many companies use PET plastics to make long-term storge containers for water and food.

When compared to glass production, PET manufacturing practices are greener. Unlike glass, PET packaging uses far less energy, and it requires fewer natural resources.

In terms of food safety, PET plastics are fantastic because they have a natural protective barrier that blocks oxygen. This is why this plastic will never react to food or water.

Grade Two – HDPE

High-density polyethylene is a long-lasting, plastic material. It’s commonly used as a mold for industrial water containers.

HDPE plastics are great for water bottles too, but there are some risks. For safety reasons, it’s best to thoroughly clean the plastic first.

Grade Three – PVC

Polyvinyl Chloride or PVC is a common household plastic material. While mostly used for non-food related applications, food grade PVC is sometimes used in plastic trays or tubing.

Grade Four – LDPE

Low-density polyethylene bags have traces of chemicals. However, according to the FDA, the effects are minimal, so all LDPE bags are safe for food storage.

Grade Five – Polypropylene

Although polypropylene is lightweight, it holds up well against heat. Unlike most other plastics, polypropylene will less likely absorb chemicals when it’s used during various applications.
