Sachet & Stick Packs — OEM & Private Label

Sachets and stick packs are the ultimate convenience format — a single measured dose, no scoop, no spill, fully portable. They are the fastest-growing pack format for probiotics, electrolytes and functional powders because consumers can carry them in a bag or pocket and mix on the go. Hubogen fills sachets and stick packs in-house with precision multi-lane dosing.

Why brands choose sachets and stick packs

• Perfect portion control — one sachet is one dose, with zero measuring.
• Highly portable — ideal for travel, gym and on-the-go use.
• Great for sampling — low-cost trial units and multi-flavour variety packs.
• Protects actives — individual barrier film shields against moisture and oxygen.
• Premium shelf presence — long, narrow stick packs stand out on shelf.

Specification range

We fill 2 g to 30 g per sachet or stick pack, in three-side-seal, four-side-seal or stick-pack configurations. Barrier films include PET/AL/PE and other high-barrier laminates suitable for moisture- and oxygen-sensitive actives. Sachets can be printed in full colour and packed into cartons, display boxes or multi-serve pouches. Fill weight is set by your serving size. Non-standard barrier films add a packaging premium, confirmed at quotation.

Typical applications

Probiotic stick packs, electrolyte and hydration sachets, vitamin C and multivitamin powders, collagen peptides, mushroom and adaptogen blends, joint-support powders, sleep powders, and instant greens and superfood blends.

What decides whether a sachet project runs smoothly

A sachet is a packaging decision as much as a formulation one: the film protects the powder, and the fill accuracy defines the dose.

• Fill accuracy at small weights — the smaller the dose, the larger the relative error. Low fill weights need a different filler and more frequent check-weighing.
• Powder flow and static — fine powders and dry conditions cause static that disrupts filling. It is solved with the blend and the environment, not with the machine alone.
• Seam integrity — a sachet that leaks is a total loss in transit. Seal strength is specified, tested and recorded, not assumed.
• Barrier film choice — where the blend is hygroscopic or light-sensitive, the film is chosen against the shelf life you need, not on unit cost alone.
• Unit-dose labelling — a sachet carries a small area for mandatory text. That space is a design constraint and should be considered before artwork starts.

Sourcing and specification notes

• Stick packs give a precise single serving and excellent barrier protection, at a higher unit cost than a tub.
• The fill system suits powders and granules; a paste or a very sticky blend needs a different line.
• Barrier film choice is a shelf-life decision — metallised and foil laminates protect sensitive actives far better than a standard film.
• Narrow fill weights have a tight tolerance window, so in-line weight verification is standard on this format.
• Stick packs are strong for subscription and travel positioning because the serving is fixed and the pack is portable.
• Child-resistant and tear-notch opening features are available and affect the pack dimensions.

What we check before a sachet batch is released

Every run leaves the plant against a written release protocol rather than a visual inspection. We measure the critical physical parameters across the whole batch, because a product that starts the run on spec and drifts by the end is an inconsistency problem even when the average looks correct. Uniformity is checked on the finished unit, not just on the bulk blend, so what your customer opens matches what we tested.

Moisture, hardness or viscosity — whichever governs your format — is checked against the specification agreed at quotation stage. Heat-sensitive actives are processed at a temperature set against the ingredient, not against the line's convenience, and where an active sits near the limit of what the format tolerates we say so before the batch rather than after the assay.

Stability behaviour is verified on the finished pack so that month-three behaviour is known before shipment. The retained sample is held so your reorder can be matched on appearance, texture and fill weight rather than on the label alone.

Packaging and shelf life for sachets

Packaging is chosen against your channel: bottles and jars for retail and e-commerce, pouches, sachets and stick packs for single-serve and subscription models, bulk supply for brands that fill and label in their own market. The closure and the barrier matter as much as the container, because most shelf-life failures are moisture or oxygen ingress through the pack rather than a fault in the product.

Shelf life is stated on your specification sheet and confirmed against the stability data for the specific formulation rather than quoted as a general rule for the format. Storage guidance travels with the COA so your warehouse and your end customer handle the product the same way.

Procurement notes for first-time buyers

A supplement programme usually fails on the details nobody wrote down, not on the dosage form itself. The buyers we work with who move fastest are the ones who bring four things to the first call: the target market, the actives and their dosages, the pack count they intend to sell, and the label claim they want to make. With those four in hand we can name a formulation route, a batch size and a lead time on the same call. Without them, every answer becomes a range and every quote becomes provisional.

Three habits separate smooth programmes from expensive ones. First, sample before you commit: a pre-production sample validates taste, texture, dissolution and shelf behaviour far more cheaply than a rejected bulk run. Second, freeze the artwork before the batch starts, because a packaging change mid-run resets the line and can reset the lead time with it. Third, ask for the specification sheet and COA at quotation stage rather than at shipment, so your own regulatory review runs in parallel with production instead of behind it.

Documentation travels with every order: certificate of analysis, material safety data sheet, specification sheet and free artwork support for your own logo. Certification support covers HACCP, ISO 22000, HALAL, cGMP and US FDA Food Facility Registration. Because formulation, filling, packaging and QC all sit inside our own plants in Zhengzhou, there is no handoff between vendors and no split accountability when a question needs an answer.

If you are comparing suppliers, the useful test is not the headline price but how each one answers the awkward questions — what happens if the fill weight drifts, who owns the shell or coating decision, how long a reorder actually takes. Send us your specification and we will answer those directly, in writing, before you place anything.
