Granule Sachet Manufacturer for Custom Supplement Stick Packs

EUPHM runs four vertical form-fill-seal lines dedicated to granules and powders. Each line fills 40–60 sachets per minute, with a fill weight range of 2 g to 30 g. Servo auger dosing holds accuracy to ±2%, which matters for active ingredients dosed below 500 mg per sachet. Changeover between stick packs and 3-side seal sachets takes under 90 minutes. Nitrogen flushing is available for oxidation-sensitive blends.

Secondary packaging includes 10, 14, 20 or 30 sachets per carton, with optional child-resistant closures or single-serve tear notches. We also run bulk sachet filling into 500 g or 1 kg pouches for sampling or professional channels. Retail bottling remains available on separate lines if your brand sells both formats. MOQ for retail cartons is 1,000 units per SKU; pilot runs start at 1,000 units.

Granule blends are sensitive to particle size, flowability and hygroscopicity. EUPHM accepts actives including prebiotic fibres (inulin, FOS, GOS), electrolyte salts, collagen peptides, vitamin C, zinc, magnesium citrate, herbal extracts and probiotic blends at 1–10 billion CFU per sachet. We screen and mill raw materials to 40–80 mesh before blending, then use fluid-bed granulation or dry granulation depending on heat and moisture sensitivity.

Flavours and sweeteners are matched to your target profile: stevia, monk fruit, sucralose, erythritol or sucrose. Typical granule sachet formulations contain 70–90% carrier (maltodextrin, isomalt, or rice flour), 5–20% active blend, and 1–5% flavour and flow agent. We provide a formulation review within 5 working days of receiving your target dosage. Stability testing at 40°C/75% RH for 3 months is available before scale-up.

The plant holds GMP, ISO 22000 and HACCP certifications. Halal and vegan certifications are available per SKU. EUPHM operates as an FDA-registered facility for US-bound shipments. Every batch is tested for micro counts, heavy metals, fill weight and seal integrity. Certificates of analysis are issued per lot. Retain samples are kept for 24 months.

Export documents include commercial invoice, packing list, certificate of origin, health certificate and halal certificates where applicable. We ship FOB Shenzhen or Hong Kong, with air freight for samples and sea freight for full orders. Typical sea transit to US West Coast is 18–24 days; to Rotterdam 28–32 days; to Jebel Ali 16–20 days. DDP terms are available for repeat buyers.

Every granule sachet batch is tested against a written specification before release. Incoming raw materials are sampled at 100% of containers for identity by FTIR or HPLC, and composite samples are tested for potency, microbials (total plate count, yeast and mould, E. coli, Salmonella), heavy metals (lead, cadmium, arsenic, mercury) and, where applicable, disintegration. In-process checks run every 30 minutes on fill weight, seal integrity and sachet appearance. Finished sachets are tested for potency, microbials and moisture, with results recorded on the batch record.

A certificate of analysis (COA) accompanies each batch and states the product name, lot number, manufacture and expiry dates, tests performed, specifications, results and pass/fail status. It is signed by the QC manager and references the analytical methods used. Retention samples of every batch are kept for 24 months at controlled room temperature, and additional samples are stored under accelerated conditions (40°C/75% RH for 3 months) and intermediate conditions (30°C/65% RH for 6 months) to support the 18–24 month shelf life claim.

Stability protocols follow ICH Q1A(R2) principles adapted for dietary supplements. Real-time studies run for the declared shelf life, with testing at 0, 3, 6, 12, 18 and 24 months. Accelerated studies screen for formulation weaknesses before a batch is committed. If a batch fails any specification, it is quarantined, an investigation is opened and a deviation report is issued. Release only occurs after QC manager sign-off and, for export orders, a pre-shipment review of the batch record and COA.

Granule sachets can be packed in retail cartons, stick packs, 3-side seal sachets, bottles or bulk drums. Stick packs are typically 20–30 mm wide with a tear notch and are packed 10, 20 or 30 per carton. Bottles are available in 60, 120 or 180 cc HDPE with induction seals, and blisters are available for unit-dose formats. Cartons are printed with a full FDA dietary-supplement label, including supplement facts, ingredient list, allergen statement, net quantity, lot code and expiry date. Lot and expiry coding is applied by inkjet or laser at the filling line.

For Amazon FNSKU and retail compliance, we apply FNSKU labels, poly-bag the cartons where required, and print carton dimensions and weight on the master case. Master cartons are 5-ply corrugated, with a maximum weight of 15 kg, and are palletised at 1,200 × 1,000 mm or 1,200 × 800 mm. Each pallet is stretch-wrapped and labelled with the pallet ID, batch number and quantity. We can also provide a packaging specification sheet with dimensions, material composition and recycling codes for retailer onboarding.

Label artwork is checked against the approved formula and the destination market’s labelling rules before printing. For the US market, we verify that the supplement facts panel, serving size and % daily value are consistent with the formula. For the EU, we check allergen declarations and nutrition claims. We do not print claims that are not supported by the product specification. Artwork proofs are signed off by the customer, and a retained copy is kept with the batch record.

Sampling starts with a 7–10 working day turnaround after formula and packaging approval. The sample includes the granule blend in the proposed sachet, a draft COA and a packaging mock-up. Once the sample is approved in writing, mass production runs 20–35 working days, depending on raw material lead times and line scheduling. MOQ is 1,000 units per SKU for retail cartons and 1,000 units for pilot runs. For orders above 50,000 units, we can schedule dedicated line time and reduce the production window to 18–25 working days.

Shipping is by air or sea. Air freight is typically 5–8 days door-to-door for 100–500 kg orders, while sea freight is 25–35 days port-to-port for full containers. We quote EXW, FOB Shenzhen or Hong Kong, and DDP for selected destinations. DDP includes customs clearance and delivery to the customer’s warehouse, with duties and taxes billed at cost. For sea shipments, we provide a packing list, commercial invoice, bill of lading and, where required, a certificate of origin.

Export documents include the COA, material safety data sheet (MSDS) where applicable, free-sale certificate, and phytosanitary certificate for plant-derived ingredients. We also provide a halal certificate if the product is produced under a certified programme. Documents are issued within 3 working days of shipment. For repeat orders, we keep the approved artwork, formula and batch records on file so that reorders can be processed without re-sampling.
