750ml PET Drink Bottle with Lid

Dry or wet, organic or chemical, products of all sorts can come packed in a PET container. The light and durable plastic makes for convenient and protective packaging for supplement capsules, superfood powders, lotions, creams, and more. However, keep in mind that proper testing is advisable to see if the material is suitable for your specific 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, the container itself is waterproof. But in practice, it is only impervious with the right cap. For instance, caps without liners or with PS 22 (pressure-sensitive) liners are not best suited for liquids. EPE and induction liners, on the other hand, are the perfect solution for water-based products.

Whatever is dry or solid. The pressure-sensitive liner creates a protective barrier from moisture for your supplement powders, pills and gummies. The seal needs a dry bottle surface, though, so the PS 22 liner is not recommended for liquids.

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 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.

If you’re looking for a child-resistant cap (CRC), the pharmacy cap should be your choice. The user must push it down and twist to open, which makes it challenging for a child. Since this cap type is required for certain over-the-counter drugs, it is generally a good enough seal to protect from external contamination.
