A sachet may be one of the smallest packages in a product range, but it is rarely the simplest to specify.
The package must hold an accurate portion, run smoothly on filling equipment, seal through fine powder or product residue, protect a relatively small quantity of product and still leave enough space for branding, instructions and regulatory information.
Custom sachet packaging is a sealed flexible package made to a brand’s required size, material structure, barrier level and printed design. It is commonly used for single servings, samples, trial products and controlled doses of coffee, tea, drink mixes, supplements, seasonings, sauces and personal-care products.
Unlike a standard stock sachet, a custom sachet can be developed around the actual product rather than forcing the product into an existing package.
At BioPack, we normally begin a sachet project with five questions:
What product will be packed?
How much goes into each sachet?
What shelf life is expected?
How will the sachet be filled and sealed?
What environmental claim will be made in the destination market?
These questions determine far more than the dimensions. They influence the film structure, sealant layer, barrier performance, opening method, printing process and final packaging cost.
A sachet is a small flexible package sealed around its edges or along a back seam. It is generally designed to contain one serving, one application or a small product sample.
Custom sachets can be supplied as:
Preformed sachets for manual or semi-automatic filling
Connected sachets with perforations
Custom-shaped packs for promotional products
The buyer can specify the dimensions, fill volume, packaging material, barrier level, seal layout, printing, surface finish and opening feature.
This makes sachet packaging suitable for products that need more than a generic plastic wrapper. Ground coffee, for example, may need aroma and oxygen protection, while an electrolyte powder may be more sensitive to moisture. A sauce sachet introduces different sealing and chemical-compatibility requirements again.
The package should therefore be engineered around the product, not selected only by appearance.
One of the main benefits of sachet packaging is portion control. Each unit can contain a measured quantity for one preparation, serving or application.
Giving away a full retail pouch is often too expensive. Filling an unbranded stock bag may be cheaper, but it does little to communicate the value of the product.
Custom printed sachets provide a middle ground. They allow brands to distribute a useful amount of product while keeping the brand name, product information and preparation instructions visible.
Sachets are lightweight, compact and easy to carry. Consumers can place them in a handbag, office drawer, lunchbox, gym bag or travel kit.
The opening experience matters just as much as portability. A tear notch that does not start cleanly can spill powder, while a notch positioned too close to the product area can weaken the package.
A custom printed sachet gives the brand control over both the appearance and the information hierarchy.
Flexible sachets use little storage space before filling and usually weigh less than small rigid jars, bottles or tubs.
Their flat format can improve carton utilization for samples, travel products and single-use portions. However, lower weight alone does not prove that a package is environmentally preferable.
There is no universal “best sachet material.”
At BioPack, we compare structures based on the product, filling process, barrier requirement, destination market and intended environmental message.
BioPack’s current sustainable flexible packaging portfolio includes certified compostable films, recyclable mono-PE structures, PCR-containing films and paper-based laminates for coffee, tea, snacks, dried foods, powders and supplements.
Traditional sachet films often combine several layers.
Each layer performs a different job: one may provide print quality and stiffness, another may provide oxygen or light protection, and the inner layer creates the heat seal.
These laminates can deliver dependable performance, but combining incompatible materials can make recycling difficult.
They may still be the practical choice for highly sensitive or demanding products when no validated lower-impact structure provides the required shelf life.
The answer depends on the product and the end-of-life system.
A recyclable mono-material sachet may be the stronger choice when:
The product requires dependable moisture protection
PE film collection is available in the destination market
The brand has a plastic-circularity strategy
The complete structure can remain compatible with recycling guidance
A compostable sachet may be more appropriate when:
The finished structure has relevant certification
Composting supports the product and brand positioning
Appropriate collection and composting infrastructure exists
The required shelf life can be achieved
Disposal instructions can be communicated clearly
Neither choice should come before product protection.
Packaging that causes flavor loss, moisture damage or premature spoilage may create more waste than it prevents. The first responsibility of a food or supplement sachet is still to protect its contents.
Share the product type, ingredients, particle size, oil content, moisture sensitivity, fill temperature and expected shelf life.
Do not choose the final sachet dimensions only from a competitor’s package.
The density of the product affects the required volume. Ten grams of one powder may occupy considerably more space than ten grams of another.
Confirm whether the sachets will be.
For machine-packed sachets, provide the machine model and current film specification whenever possible.
The expected shelf life affects the barrier requirement and material choice.
Storage temperature, humidity, light exposure and distribution conditions should be considered. A sachet used for a two-week sampling campaign may not need the same structure as a retail product expected to remain stable for eighteen months.
Choose the environmental objective only after confirming the product requirements.
Possible directions include mono-material PE, certified compostable film, PCR content and paper-based appearance.
The most marketable claim is not always the most suitable technical solution.
Depending on the project, testing may include:
Material compatibility
Filling-line trial
Seal-strength test
Leakage test
Drop or compression test
Opening test
Packed-product shelf-life test
Print proof and color approval
The final approval should be based on a filled package whenever possible.
Custom sachet packaging can be developed with:
Three-side, four-side or fin seals
Stick pack dimensions
Custom width and length
Transparent or metalized barriers
Matte, gloss or soft-touch finishes
Digital or gravure printing
Hang holes
Transparent windows
QR codes
Multiple designs within one product range
Not every feature is compatible with every material. For example, adding a window, coating or special finish can affect recyclability or compostability.
Our role as a packaging supplier is to identify these trade-offs before production, not after the packaging has entered the market.
BioPack develops custom sustainable flexible packaging for organic food, coffee, tea, snacks, dried products, powders, supplements and wellness brands.
We do not begin every project by recommending the same “eco” material.
Instead, we compare the product requirement with the available compostable, recyclable, PCR and paper-based structures. We also consider printing, filling, order volume, destination market and the environmental message the customer intends to communicate.

What is custom sachet packaging?
Custom sachet packaging is a small flexible package manufactured in a specified size, material, barrier structure and printed design. It is generally used for single servings, samples, controlled doses and travel-size products.
What products can be packed in sachets?
Sachets can hold powders, granules, liquids, pastes and small solid products. Common applications include coffee, matcha, tea, protein powder, collagen, vitamins, electrolytes, spices, sauces and cosmetic samples.
What is the difference between a sachet and a stick pack?
A sachet is usually wider and more rectangular. A stick pack is narrow and elongated, making it convenient for powders that need to be poured into a bottle, cup or shaker.
Can custom sachets be recyclable?
Selected sachets can be developed as mono-material PE structures. Recyclability must be assessed using the complete package design and the collection system available in the destination market.
Can sachets be compostable?
Yes. Selected dry food, coffee and supplement sachets can use certified compostable films. The certification scope, barrier performance and access to industrial or home composting should be verified before making a claim.
Are paper sachets plastic-free?
Not necessarily. Many paper sachets need a coating or inner film to create a heat seal and protect the product. The full structure must be reviewed before the package is described as plastic-free.
Can BioPack produce low-volume custom printed sachets?
Lower-volume digital printing may be available for selected sachet materials, sizes and designs. The practical minimum quantity depends on the film structure, printing method and converting process.
How do I choose the right barrier?
The barrier should be based on the product’s sensitivity to oxygen, moisture, light and aroma loss, together with the required shelf life and storage conditions. Testing the packed product is recommended before full production.
Can BioPack supply sachet roll stock?
Yes. Printed roll stock can be developed for suitable form-fill-seal machines. Machine specifications, web direction, repeat length, registration marks and sealing conditions should be confirmed before production.
What information is needed for a quotation?
Provide the product type, fill weight, sachet dimensions, order quantity, filling method, shelf-life target, material preference, artwork quantity and shipping destination.
