120ml 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.

That’s right! Polyethylene Terephthalate (PET) is a fully recyclable material. After serving its purpose, a bottle made from this type of plastic can be transformed into a different container or used as a component in clothing, homeware, and much more.

PET is approved by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) for use in food packaging. To keep your products in the best shape, store your containers in a cool and dry place.

PET plastic is completely impervious. This is not to say that every type of cap for your container will be waterproof. Caps without liners or with PS 22 (pressure-sensitive) liners are not the best option for liquids. If your product is water-based, opt for an EPE or induction liner instead.

This liner type is usually ideal for dry and solid products such as powders and pills. The PS 22 seal can effectively preserve the dryness of your product. It is not waterproof, though, since the liner requires a dry surface on the bottle to stick.

One of the most affordable options, the EPE is a multi-purpose liner that effectively prevents leaks. You can safely use it for your water-based supplements. However, keep in mind that this liner cannot create an airtight seal like the induction liner will.

The induction seal cap is the most secure and tamper-evident closure option for your products. The liner is applied to the container with the use of an induction sealing machine, which makes it impossible to re-apply once meddled with. This airtight and hermetic seal perfectly protects the freshness of pharmaceuticals (pills, tablets, capsules), personal care products (creams, gels, lotions), food (both dry & liquid), and more. The liner comes plain or printed with a custom message, such as “sealed for your protection”.

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.
