Introduction
The five most common gummy packaging issues are sticking and clumping, moisture loss and hardening, discoloration, breakage during shipping, and label compliance failures — each solvable with targeted formulation adjustments, high-barrier packaging materials, and proper process controls.
Industry data shows that 60–80% of gummy brands encounter at least one packaging-related quality issue in their first year of sales, particularly when exporting to North American and European markets where temperature fluctuations during ocean transit and strict FDA/EFSA labeling regulations compound the risk.
When it comes to gummy products, the importance of packaging cannot be overstated. It serves as far more than just a "wrapper" or marketing vehicle — it is the critical line of defense that preserves product quality, extends shelf life, and ensures a positive consumer experience. A perfectly formulated, great-tasting gummy can lose all its appeal if poor packaging design leads to issues like sticking, hardening, discoloration, or breakage by the time it reaches consumers. When that happens, all upfront R&D investment and marketing efforts can go to waste.
In actual production, many brands focus their energy on formulation and flavor while underestimating the importance of packaging. They only scramble to address problems after products hit the market, which both increases costs and damages brand reputation. This is especially true for brands targeting North American and European markets, where in addition to solving functional packaging issues, products must also meet strict labeling compliance requirements. A single misstep can result in products being pulled from shelves or even legal risks.
This article systematically reviews the most common types of gummy packaging problems, analyzes their root causes, and provides practical solutions to help brands mitigate risks from the design stage onward — ensuring great products are paired with great packaging.
Why Packaging Is Critical for Gummy Products
Gummies are an environmentally sensitive product format. Their compositional characteristics make them vulnerable to temperature, humidity, light, oxygen, and other factors. The core function of packaging is to create a relatively stable micro-environment for gummies that shields them from external influences.
Specifically, gummy packaging serves the following important functions:
Protecting product quality: It blocks moisture, oxygen, light, microorganisms, and other adverse factors, maintaining the texture, flavor, and active functional ingredients of gummies to ensure stable quality throughout the shelf life.
Ensuring transportation safety: During long-distance shipping and multiple handling processes, packaging protects gummies from compression, impact, temperature fluctuations, and other factors, reducing breakage rates.
Conveying brand value: Packaging is the first point of contact between consumers and the product. Well-designed packaging elevates product positioning, communicates brand identity, and influences purchasing decisions.
Meeting compliance requirements: Especially for products exported to overseas markets, ingredient lists, nutrition claims, warning statements, barcodes, and other elements on packaging must comply with local regulations. Otherwise, products cannot clear customs or be sold on shelves.
Common Issue #1: Sticking / Clumping
Problem Manifestation and Impact
Sticking (also called "clumping" or "agglomeration") is one of the most common packaging problems with gummies. When consumers open a bottle and find gummies stuck together — or even fused into a single mass — the experience is extremely poor, often leading directly to negative reviews or refund requests. Sticking issues are particularly prominent during summer high-temperature conditions and long-distance ocean shipping.
Root Cause Analysis
The essence of gummy sticking is surface tackiness that causes individual pieces to adhere to each other. Specific causes include:
Excessively high water activity: When gummy moisture content or water activity is too high, sugars absorb moisture and become tacky on the surface.
High temperatures: In high-temperature environments, sugars in gummies (especially low-melting-point sugars) soften or even melt, causing sticking. Summer transportation or improper warehouse temperature control are peak periods for sticking problems.
Formulation factors: Certain formulations are inherently more prone to tackiness, such as those with high fructose corn syrup content or strongly humectant sugar substitute formulations.
Missing or insufficient coating: The sugar coating, oil film coating, or polishing layer on gummy surfaces not only enhances appearance but also serves as a barrier against sticking. When the coating process is inadequate, gummies are more likely to stick together.
Solutions
Optimize gummy surface treatment:
- Sanding: Evenly coat gummy surfaces with fine granulated sugar or sour sugar to form a physical barrier that both prevents sticking and enhances mouthfeel
- Glazing / Polishing: Use glazing agents or polishing processes to form a smooth protective film on gummy surfaces
- Release oil / release wax: Use appropriate amounts of food-grade release agents to reduce adhesion between gummies
Control water activity: Through formulation adjustments and drying processes, control gummy water activity within a reasonable range to reduce the risk of surface tackiness.
Select appropriate packaging materials:
- Use high moisture-barrier packaging materials to reduce external moisture entering the package
- Place desiccants inside bottles to absorb excess moisture within the package
- Pay attention to desiccant selection and dosage — it must effectively dehumidify without over-drying and causing gummies to harden
Temperature control during transportation and storage: For exported products, choose temperature-controlled containers or air freight whenever possible to avoid high-temperature shipping. If ocean freight is necessary, ensure high-temperature resistance is designed into both the formulation and packaging.
Common Issue #2: Moisture Loss / Hardening
Problem Manifestation and Impact
The opposite of sticking, some gummies gradually lose moisture and harden during their shelf life, losing their original soft, chewy texture and becoming difficult to bite or even inedible. This problem is more likely to occur in dry climates and seasons, severely affecting consumer experience and product reputation.
Root Cause Analysis
Poor packaging seal performance: Insufficient moisture barrier of packaging materials or improper sealing causes moisture inside the package to continuously escape.
Imbalance between water activity and environment: When environmental humidity is lower than the equilibrium humidity corresponding to the gummy’s water activity, moisture in the gummies continuously migrates to the environment until a new equilibrium is reached. During this process, gummies gradually lose moisture and harden.
Formulation factors: Certain formulations have poor moisture retention — for example, sugar-free gummies with high erythritol content are more prone to moisture loss and hardening.
Solutions
Improve packaging seal performance:
- Choose high moisture-barrier packaging materials such as aluminum foil composite films and high-barrier plastic bottles
- Ensure consistent sealing quality to prevent air leakage
- For bottled products, the selection of bottle neck sealing gaskets is critical
Formulation-level moisture retention optimization:
- Add appropriate amounts of humectants (such as glycerin, sorbitol, etc.) to the formulation to improve the water-holding capacity of gummies
- Adjust the sugar system to select sugar combinations with better moisture retention
- Optimize the colloid system to enhance the water-locking ability of the gel network
Control water activity: Based on the climatic conditions of the target market, reasonably set the product’s water activity to avoid excessive gaps with environmental humidity.
Rational use of desiccants: More desiccant is not necessarily better. Over-drying can actually accelerate moisture loss in gummies. Desiccant dosage must be precisely calculated based on package size, gummy moisture content, and target water activity.
Common Issue #3: Discoloration / Flavor Loss
Problem Manifestation and Impact
Gummies gradually fading in color and becoming dull during shelf life, or losing flavor and developing off-notes, are problems no brand wants to see. This is especially true for products using natural colors and natural flavors, where discoloration and flavor loss are more pronounced. While these issues do not involve safety risks, they seriously affect the product’s visual appeal and taste experience, reducing consumers’ repurchase intention.
Root Cause Analysis
Light exposure: UV light is the "natural enemy" of natural colors and flavors. Light accelerates pigment decomposition and flavor oxidation, leading to fading and flavor deterioration.
Oxidation reactions: Oxygen reacts with pigments, flavors, and oil-based components in gummies, causing discoloration, flavor degradation, and even rancidity. For gummies containing oils or easily oxidizable functional ingredients, oxidation is the primary quality degradation factor.
Temperature effects: High temperatures accelerate the rate of almost all chemical reactions, including pigment decomposition, flavor volatilization, and oxidation reactions. The higher the storage temperature, the faster discoloration and flavor loss occur.
Maillard reaction: The Maillard reaction between reducing sugars and amino acids/proteins under certain conditions can cause gummies to darken in color and change in flavor.
Solutions
Light-blocking packaging:
- Use opaque or semi-transparent packaging bottles/bags to block UV light
- For transparent packaging requirements, choose packaging materials with added UV absorbers
- Add light-blocking layers to outer box design
Oxygen barrier and antioxidation:
- Use high-barrier packaging materials to reduce oxygen permeation
- Use oxygen absorbers to remove free oxygen inside the package
- Nitrogen-flushed packaging: Fill the package with nitrogen to displace oxygen and create an oxygen-free environment
- Add appropriate amounts of antioxidants (such as vitamin E, vitamin C, etc.) at the formulation level
Optimized selection of flavors and colors:
- Choose more stable varieties of colors and flavors
- Use microencapsulation technology to protect flavors and colors from external environmental influences
- Appropriately increase addition levels to provide a margin for attenuation
Storage condition control: It is recommended that products be stored in a cool, dry place, away from high temperatures and direct sunlight. Storage conditions should also be clearly marked on product labels.
Common Issue #4: Shipping Damage
Problem Manifestation and Impact
Although gummies are soft food products, they can still experience damage during transportation. Especially for gummies with complex shapes and relatively brittle textures, after long-distance transportation and multiple handling, issues such as cracking, deformation, and coating loss may occur. The poor "appearance" when consumers open the bottle seriously damages brand image.
Root Cause Analysis
Physical impact and vibration: Mechanical forces such as bumping, vibration, and dropping during transportation can cause gummies to crack or deform.
Compression deformation: Excessive internal space in packaging causes gummies to collide and squeeze against each other during transportation; or insufficient outer carton strength leads to crushing during stacking, indirectly compressing the product.
Temperature-related damage: High temperatures soften gummies, making them more prone to deformation and sticking under external force; low temperatures harden and make gummies brittle, making them more susceptible to cracking.
Solutions
Packaging cushioning design:
- Bottled products: Choose appropriate bottle sizes to avoid excessive empty space inside the bottle that causes gummies to shake too much
- Bag packaging: Consider using individual small packages to reduce friction and collision between pieces
- Insert / divider design: For premium products, use inserts to hold gummies in place and reduce collision during transportation
Outer carton strength design:
- Based on stacking height and transportation method, select corrugated grades and outer cartons with appropriate strength
- Optimize packing methods to ensure cartons are full and free of gaps, reducing movement during transportation
- Use corner protectors and edge reinforcement measures to improve the impact resistance of outer cartons
Formulation and process optimization:
- Optimize gummy texture to improve toughness and shatter resistance
- For coated gummies, optimize coating adhesion to reduce coating loss during transportation
- Adjust formulation for high/low temperature resistance based on transportation environment temperatures
Packaging Compliance Considerations
Beyond functional issues, packaging compliance is equally important. Especially for products exported to North American and European markets, packaging labels are subject to very strict regulatory requirements:
Ingredient and Allergen Labeling
- All ingredients must be fully listed in descending order of predominance by weight, as required by regulations
- The top eight allergens (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans) must be clearly declared
- Pay attention to usage guidelines for precautionary allergen labeling such as "may contain"
Nutrition Facts Panel
- Nutrition labeling must follow the format requirements of the target market (e.g., Nutrition Facts Panel in the US, Nutrition Declaration in the EU)
- Core nutrients must be declared: calories, total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrates, dietary fiber, total sugars, added sugars, protein, and more
- Nutrition claims (such as "sugar-free," "low-calorie," "high-fiber," etc.) must meet corresponding content standards and cannot be made arbitrarily
Functional Claims
- Dietary supplement efficacy claims are strictly regulated and cannot promote therapeutic effects
- The US market must comply with FDA Structure/Function Claim rules and include appropriate disclaimers
- The EU market must comply with EFSA regulations
Other Compliance Requirements
- Net content declaration position, format, and precision requirements
- Production date, shelf life, and batch number labeling specifications
- Manufacturer information and importer information labeling requirements
- Proper application of barcodes (UPC/EAN)

Frequently Asked Questions
What is the most common gummy packaging problem?
Sticking and clumping is the most common gummy packaging issue, affecting up to 70% of brands. It occurs when gummies fuse together in the bottle, usually due to high water activity, warm shipping temperatures, or inadequate surface coating. Solutions include sugar sanding, glazing, moisture-barrier bottles with desiccants, and temperature-controlled shipping.
How do you prevent gummies from hardening in the bottle?
Gummies harden when moisture escapes through poor packaging seals. Prevent this by using high moisture-barrier packaging materials (such as PET bottles with induction seals), controlling water activity during formulation, and including appropriate humectants. For dry climates, avoid over-drying during production and use properly sealed primary packaging.
What packaging compliance requirements apply to gummies sold in the US?
Gummies sold in the US must comply with FDA labeling rules, including a full ingredient list (in descending order by weight), nutrition facts panel, allergen declarations, supplement facts if classified as dietary supplements, and proper lot codes and expiration dates. Functional claims must also be compliant. Packaging must be tamper-evident and child-resistant where required.
How does packaging affect gummy shelf life?
Packaging directly determines gummy shelf life by controlling moisture, oxygen, and light exposure. Premium barrier packaging with proper sealing can extend shelf life from 12 months to 18-24 months. Key factors include moisture vapor transmission rate (MVTR) of materials, induction seal quality, desiccant use, and UV protection for light-sensitive ingredients.
What is the minimum order quantity for custom gummy packaging?
Custom gummy packaging MOQs vary by format: standard stock bottles typically start at 500 units, while fully custom-printed bottles start at 5,000-10,000 units. For custom pouches or blister packs, MOQs range from 10,000-50,000 units. Many manufacturers like Subeau offer 500-bottle MOQs with label customization for brands just starting out.
