Packaging Options for Export Gummies: Protecting Stability and Brand
A brand shipped a container of premium probiotic gummies from India to the UAE. They had chosen a beautiful, clear PET bottle to show off the vibrant natural colour of the gummies. By the time the shipment cleared customs and reached the distributor’s non-climate-controlled warehouse, the damage was done. Moisture had permeated the thin plastic walls. The gummies had fused into a single, sticky block, and the probiotics had died.
The brand lost the entire shipment, not because of a manufacturing error, but because of a packaging choice.
When producing gummies for export - particularly to regions with high humidity or extreme temperature fluctuations - packaging is not just a marketing vessel. It is a critical, structural component of the product’s shelf life.
If you are finalizing your product specifications, here is a definitive guide to packaging options for export gummies and how to ensure your choices protect both your stability data and your brand equity.
The Enemy of the Gummy: Moisture Migration
Gummies are high-moisture systems. Their stability depends on maintaining a very specific water activity (Aw) level.
If the environment outside the bottle is more humid than the inside, moisture will migrate through the packaging and into the gummy. The gummies will become sticky, "weep" liquid, and become a breeding ground for microbes. The added moisture will also rapidly degrade sensitive vitamins and probiotics.
Conversely, if the environment is very dry, moisture will migrate out of the gummy. The gummy will harden, losing its chew and becoming unpleasant to eat.
Your packaging must act as an absolute barrier to this moisture exchange.
Primary Packaging: The Bottle Selection
The bottle material is the first line of defense. Not all plastics offer the same barrier properties.
1. High-Density Polyethylene (HDPE)
The Industry Standard for Stability. HDPE is opaque, rigid, and provides an excellent Moisture Vapor Transmission Rate (MVTR) barrier. It is the safest choice for exporting functional gummies, particularly those containing moisture-sensitive actives like probiotics or Vitamin C. While it doesn't allow the consumer to "see" the gummies, it guarantees the product will survive long transit times.
2. Polyethylene Terephthalate (PET)
The Marketing Choice with Risks. PET is clear, allowing the bright colours of the gummies to shine through. However, PET has a significantly poorer MVTR than HDPE. Moisture will slowly pass through the plastic over time. If you absolutely must use PET for marketing reasons, you must compensate:
- Use a thicker-walled PET bottle.
- Increase the desiccant size inside the bottle.
- Do not use clear PET for light-sensitive ingredients (like Vitamin K2 or certain B vitamins) unless it includes a UV-blocking tint.
3. Glass
The Premium/Eco Choice. Glass provides a perfect barrier against moisture and oxygen. It feels heavy and premium. However, it is rarely recommended for export gummies. Glass is heavy (increasing shipping costs exponentially), fragile (breakage during sea freight is common), and expensive.

The Closure System: Locking the Barrier
A high-barrier bottle is useless if the lid leaks air. The closure system is just as important as the bottle material.
Child-Resistant (CR) Caps
Required by law in many markets (like the US and UK) for products containing certain levels of specific vitamins (e.g., iron). Even if not legally required, CR caps are often expected by major retailers. Ensure your contract manufacturer’s automated capping lines can handle CR caps at commercial speeds.
The Induction Seal (Non-Negotiable)
This is the foil or plastic seal fused to the rim of the bottle under the cap. Never export a gummy without an induction seal. The induction seal provides tamper evidence (a regulatory requirement) and hermetically seals the bottle, preventing any moisture or oxygen exchange until the consumer opens it. If your CMO uses cheap, pressure-sensitive foam liners instead of heat-welded induction seals, your product will degrade during transit.
Internal Protection: Desiccants
Every bottle of exported functional gummies should contain a desiccant.
A desiccant (usually a silica gel packet or a clay canister) absorbs any ambient moisture that was trapped in the headspace of the bottle during the filling process, as well as any moisture that breaches the seal after the consumer opens the product.
For probiotic gummies, the desiccant is not optional - it is a survival mechanism for the bacteria. The size of the desiccant (e.g., 1g, 2g, 3g) must be calculated based on the volume of the bottle and the moisture sensitivity of the active ingredients.
Secondary Packaging for Export
Secondary packaging protects the primary bottle during logistics and handling.
Cartons vs. Shrink Sleeves
Many brands are moving away from individual cardboard cartons to reduce cost and environmental impact, opting instead to label the bottle directly and use a clear tamper-evident shrink band over the neck. However, for premium products or products destined for European pharmacies, an individual folding carton is still often required for retail display and to provide enough surface area for multi-language regulatory text.
Master Cartons and Palletizing
Ensure your CMO uses heavy-duty, double-walled corrugated master cartons. Sea freight subjects pallets to immense crushing forces. If the master cartons are cheap, the bottom layers will collapse, damaging the individual bottles inside.
Furthermore, the pallet must be tightly shrink-wrapped and edge-protected. If the shipment is going to a high-heat region (like the GCC), ask your freight forwarder about thermal pallet covers to mitigate temperature spikes on the tarmac.

The Cost of Getting it Wrong
Upgrading from a cheap PET bottle with a foam liner to a premium HDPE bottle with an induction seal and desiccant might add $0.15 to $0.25 to your unit cost.
However, launching a product with inadequate packaging leads to:
- Failed stability tests at Month 6.
- Massive retail return rates due to melted or hardened gummies.
- Loss of entire shipping containers due to moisture damage during sea freight.
- Permanent damage to your brand reputation.
Do not try to save pennies on the packaging of a high-value functional formulation.
FAQ
Can I use eco-friendly or compostable packaging for gummies? Currently, most compostable or plant-based plastics do not provide an adequate moisture barrier for gummy supplements. They allow too much moisture transfer, causing the gummies to degrade rapidly. Recyclable HDPE or PET remains the most viable option for maintaining stability.
Do I need an induction seal if I have a shrink band around the cap? Yes. A shrink band provides tamper evidence but does not provide an airtight hermetic seal. An induction seal is required to stop moisture and oxygen from entering the bottle.
How does my choice of packaging affect stability testing? Stability testing must always be conducted in your final, commercial packaging. If you test your gummies in an HDPE bottle but launch them in a PET bottle, your stability data is completely invalid, and your stated shelf life is legally indefensible.
