Multi-Layer Gummy Manufacturer for Complex Dosage Formats

Multi-layer gummies need precise timing. If the first layer sets too far, the second layer will not bond; if it is too soft, the layers merge. Our depositing lines run 2-layer and 3-layer cycles with controlled nozzle sequencing and mould temperature. Typical output is 12,000 to 18,000 pieces per hour per line, depending on piece weight and layer count. We keep layer ratio within +/- 5% of the approved sample.

For 3-layer formats, the middle layer often carries the active while the outer layers handle flavour and texture. We can also run a centre-fill where the inner core is a liquid or soft gel. That requires a separate depositing head and a sealing layer. Line changeover between layer formats takes 4 to 6 hours, which affects scheduling on smaller runs.

The main reason to use multiple layers is ingredient separation. Vitamin C and certain probiotics degrade faster when in direct contact with minerals. A 2-layer gummy can keep them apart until consumption. Oils such as omega-3 or CBD need an emulsified layer; we use a starch-based matrix that holds up to 15% oil load by weight. Bitter actives like green tea extract or zinc go into a thin inner layer with a sweet outer shell.

Pectin and gelatin bases are both available. Pectin layers set faster and suit vegan claims; gelatin layers give a springier bite. We adjust water activity to 0.55-0.65 to protect moisture-sensitive actives. For sugar-free formats, we use maltitol or allulose syrups, though allulose layers set slower and need longer curing. Colour matching across layers is done against a Pantone reference.

Every multi-layer batch is checked for layer adhesion, weight uniformity and active content. We test the finished gummy, not just the pre-blend, because heat during depositing can degrade heat-sensitive actives. Standard testing includes micro, heavy metals, and potency by HPLC. Certificates of analysis are issued per batch. The facility is GMP-certified, ISO 22000 and HACCP compliant, and holds halal certification for relevant lines.

For export, we pack in HDPE bottles, blister packs or pouches. Bottles are induction-sealed and labelled to your artwork. We ship FOB Shenzhen or Yantian, with air freight for samples. Typical mass production runs 20-35 working days after sample sign-off. Documentation includes commercial invoice, packing list, COA, and health certificate where required. We do not claim FDA approval; the facility is FDA-registered where that applies.

Every batch of multi-layer gummies is tested against a written specification before release. Incoming raw materials are checked for identity and certificate of analysis (COA) conformity. During production, in-process checks cover layer weight, colour uniformity, texture and pH. Finished gummies are sampled from each lot for identity and potency of actives, microbial limits (total plate count, yeast and mould, E. coli, Salmonella), heavy metals (lead, cadmium, arsenic, mercury) and disintegration time. Testing follows methods such as USP <2021> for microbials and USP <2040> for disintegration, unless the client specifies otherwise.

A batch record is compiled for each production run. It includes the formulation, lot numbers of raw materials, depositing parameters, in-process results and the final COA. The COA lists the tests performed, specifications, results and pass/fail status. We retain samples from every batch for at least two years, stored under controlled temperature and humidity. Stability studies follow a standard protocol: 0, 3, 6, 12 and 24 months at 25°C/60% RH and 30°C/65% RH, with accelerated conditions at 40°C/75% RH for three months. Clients receive the stability summary with the first commercial shipment.

For multi-layer formats, additional checks focus on layer adhesion and separation. A visual inspection confirms distinct layers without bleeding. A texture analyser measures the force required to separate layers, ensuring the product holds together through shipping. If an active is sensitive to moisture or heat, we test its potency in the finished gummy at release and at the end of shelf-life. Any out-of-specification result triggers a root-cause investigation and a documented corrective action before the batch is released.

Multi-layer gummies are packed in bottles, blisters, stick packs or sachets, depending on the target market. Bottles are typically HDPE or PET with induction seals and child-resistant caps where required. Blister packs use PVC/PVDC or alu-alu for moisture protection. Stick packs and sachets are filled on vertical form-fill-seal machines, with fill weights from 2.0 g to 5.5 g per piece. We can apply lot numbers and expiry dates by inkjet or laser coding on the primary package, carton and pallet.

For the US market, labels must include the statement of identity, net quantity, supplement facts panel, ingredient list, allergen declaration and the manufacturer's name and address. We provide a label review service against FDA 21 CFR 101 requirements, but the brand owner remains responsible for final label content. For the EU, we check compliance with Regulation (EU) No 1169/2011 and health claim rules. Amazon sellers can have FNSKU labels applied and poly-bagged units prepared for FBA. Retail-ready cartons and display-ready pallets are available on request.

Cartons are specified with dimensions, board grade and print to suit the distribution channel. Standard export cartons hold 24 to 48 bottles, with a maximum gross weight of 15 kg. Pallets are 1,200 mm x 800 mm or 1,200 mm x 1,000 mm, stretch-wrapped and labelled with SSCC codes. We can ship full-pallet or mixed-SKU pallets, subject to minimum order quantities per SKU. Packaging materials are food-grade and meet EU and US food-contact regulations.

The minimum order quantity for multi-layer gummies is 1,000 units per SKU for retail bottling. pilot volumes are discussed case by case for market testing, with a surcharge. Samples are produced in 7 to 10 working days after receipt of a signed sample request and formulation confirmation. Sample costs are credited against the first bulk order. Mass production takes 20 to 35 working days after sample approval, depending on layer complexity and packaging.

We ship under EXW, FOB or DDP terms. FOB ports are Shenzhen or Hong Kong. Air freight is available for urgent orders, with transit times of 3 to 7 days to major hubs. Sea freight takes 18 to 35 days depending on destination. For DDP, we handle customs clearance and delivery to your door, with duties and taxes billed separately. All shipments include a commercial invoice, packing list, bill of lading or airway bill, COA, MSDS and a free-sale certificate. A phytosanitary certificate is provided when required for plant-derived ingredients.

Production scheduling is confirmed once the deposit is received and artwork is approved. We provide a weekly production status report. Changes to artwork or formulation after production starts may incur additional costs and delay shipment. For repeat orders, we keep master batch records and packaging films on file to reduce lead times to 15 to 25 working days.
