Choosing the right packaging for gummy supplements affects product stability, shelf life, and customer experience. The most common materials fall into four groups, each with its own trade-offs.
Common Gummy Supplement Packaging Materials
1. High-Density Polyethylene (HDPE) Jars
These are the classic rigid plastic bottles you see on supplement shelves.
- Pros: Good moisture barrier, durable and shatter-resistant, cost-effective for large runs, and opaque to protect light-sensitive ingredients.
- Cons: Bulky for shipping, usually need a desiccant packet inside to control humidity, and some consumers prefer greener options.
2. Polypropylene (PP) Jars
PP is another tough plastic, similar in form to HDPE.
- Pros: Good chemical resistance, higher heat tolerance than HDPE, and can be clear to show off the product's color.
- Cons: Slightly more permeable to moisture than HDPE, and it carries the same plastic baggage in consumers' minds.
3. Stand-Up Pouches (Mylar & Polyethylene Laminates)
Flexible, foil-lined pouches have become a popular choice for gummies. Mylar is a brand name for biaxially oriented PET film, the polyester layer used in these laminates.
- Pros: Superior barrier against moisture, oxygen, and light; lightweight and space-efficient, cutting shipping costs; often come with resealable zippers for freshness.
- Cons: Less rigid protection, which makes punctures a risk, and the multi-layer design makes recycling tough.
4. Blister Packs (PVC/PVDC or Aluminum Foil)
Individual cavities sealed with foil or film, often used for single-serving or travel packs.
- Pros: Excellent product protection and precise portion control, stronger tamper evidence, and a premium, pharmaceutical-grade feel.
- Cons: Higher per-unit cost, needs more complex packaging machinery, and uses more material per volume of product.
Child-Resistant Packaging: When It Is Required
For most gummy formulas, child-resistant packaging is optional. Under the Poison Prevention Packaging Act (16 CFR part 1700), a dietary supplement with 250 mg or more of elemental iron in a single package must ship in child-resistant packaging. The rule sums iron from all sources, and for solid forms it applies once iron reaches 0.05 percent of the product's weight. That means a multivitamin or prenatal gummy with added iron can trigger it. A compliant closure has to pass the protocol in 16 CFR 1700.20: it must resist opening by at least 85 percent of the children tested while staying openable by most adults. If your formula crosses that iron threshold, ask your packaging supplier for the child-resistance test results for the specific closure and bottle combination. For gummies without iron, child-resistant packaging remains a choice, though many brands add it anyway for safety.
Key Factors in Your Decision
Beyond material, keep these things in mind:
- Barrier Properties: Gummies absorb moisture and can dry out or get sticky. The package must block water vapor well.
- Light Protection: Many vitamins and colors are UV-sensitive, so opaque or foil-lined materials help.
- Desiccant Integration: For plastic jars, a food-safe desiccant (like silica gel) is standard to keep humidity low.
- Consumer Convenience: Child-resistant closures, easy-open tabs, and resealability make a big difference.
The best packaging material fits your product's formulation, your brand's sustainability goals, your market's preferences, and your operational needs. A well-chosen package is the final step in delivering a high-quality, stable, and appealing gummy supplement.
