150ml PET jar

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.

Absolutely. Crafted from Polyethylene Terephthalate, PET containers are 100% recyclable plastic. They are also sturdy enough to be reused multiple times for purposes other than the original.

The U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have deemed this type of plastic as good food packaging material. The best practice is to safeguard your PET containers from direct sunlight, heat and dampness.

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.

Powders, pills, spices and other dry products will be perfectly preserved by the PS 22 liner. It is not leakproof, though. The pressure-sensitive seal needs a dry land area to adhere to the bottle.

This budget-friendly liner serves as a leakproof barrier. While the EPE is a general-purpose cap liner, its true calling is liquids and water-based supplements, like lotions. If you’re looking for an airtight seal, use the induction liner rather than the EPE.

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.
