300ml PET Bottle with Lid

You can stuff PET bottles and jars with a wide range of products, solid or liquid. As these containers are both light and sturdy, they’re a handy and protective vessel for supplement powders and pills, lotions and creams, and even dry and wet foods. Please note that only appropriate testing will tell you if the PET plastic is compatible with your product.

True. PET stands for Polyethylene Terephthalate, which is a completely recyclable type of plastic. Your containers can get a new life in the packaging industry, but also in fashion or even industrial strapping.

Regulatory agencies such as the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) have approved PET for food packaging purposes. To be extra careful, store your PET bottles and jars in a cool and dry area.

Yes, but while PET plastic is impervious, not all types of caps for your container will provide a watertight seal. For liquids and water-based products, you might want to use EPE or induction liners rather than unlined caps or caps with pressure-sensitive (PS 22) liners.

The pressure-sensitive liner is typically perfect for dry or solid products: spices, powders, pills, etc. The PS 22 will maintain your dry product moisture-free but might not keep your liquids from leaking out. This liner is not waterproof because it needs a dry land area on the bottle to create a seal.

The EPE is an economical, general-purpose cap liner, often used to prevent leaking. It is a fantastic choice for all your liquids, like lotions, energy shots and water-based supplements. Unlike the induction liner, the EPE does not create an airtight seal.

The ultimate packaging protection, the induction liner comes with a tamper-evident and airtight seal. It must be applied via an induction sealing machine, so there is no chance of resealing once opened. This hermetic liner will work perfectly with dry and liquid supplements, whether it be pharmaceuticals, superfoods or cosmetics. You can pick a plain or custom seal version with a “sealed for your protection” message.

This type of cap is also referred to as a child-resistant cap (CRC), designed to be difficult for a child to open. The user must press down and twist counterclockwise. This mechanism is required for most over-the-counter medications. The cap is usually a good protection against external contaminants.
