The following are some of the most common packaging materials used in the production of supplements.


PET (Polyethylene Terephthalate)

PET is one of the most commonly used materials for supplement bottles and containers.

Benefits of PET: 

  • Lightweight and strong
  • Transparent nature that enables easy viewing of products
  • Resistant to moisture
  • Inexpensive for mass production
  • Recyclable in many places

Uses of PET include:

  • Capsules
  • Gummies
  • Tablets
  • Powder supplements

HDPE (High-Density Polyethylene)

HDPE is another popular plastic material used in supplement packaging. It is known for its strength and durability.

Benefits of HDPE:

  • Tough impact resistance
  • Moisture resistant
  • Durable enough to ship and store
  • Ideal for delicate products

HDPE is ideal for large supplement packages and bulk packaging.


PVC (Polyvinyl Chloride)

PVC is widely used in blister packaging because of its flexibility and formability.

Benefits of PVC:

  • Flexible material
  • Economical for blister packs
  • Provides good visibility of each product individually

PVC is usually used with aluminum foil in blister packs for drugs and supplements.


Aluminum Foil

Aluminum makes an ideal choice for providing a high level of barrier performance due to its ability to act as a moisture, oxygen, and light barrier.

Advantages of Aluminum Packaging:

  • Moisture barrier resistant
  • Very good oxygen barrier performance
  • Helps maintain product stability and freshness

Aluminum packaging is frequently utilized for:

  • Stick packs
  • Sachets
  • Blister packaging
  • Single serve supplement products


Glass Packaging

Glass packaging is often used for premium supplement products because of its appearance and stability.

Benefits of Glass

  • Premium look and feel
  • Strong chemical resistance
  • Excellent product stability
  • Reusable and recyclable

However, glass is typically heavier and more fragile than plastic alternatives.


Conclusion

Various packaging materials serve varying benefits depending on the product line, packaging style, and storage needs. The right choice will enhance not only the protection of your products but also their shelf-life.

It all starts with deciding whether to go for PET packaging, stick pack packaging, or any other packaging style for your supplements.
