sachets and stick packs

Sachets and stick packs have the tightest dimensional tolerance of any flexible format. On a multi lane machine running hundreds of units a minute, a small specification error becomes a large amount of waste.

Small Format, Very Little Margin

A stick pack is a narrow sleeve of film sealed on three or four sides, and the machines that make them run multiple lanes at once at high speed. That combination leaves almost no tolerance. Web width has to divide accurately across the lane count, pitch has to match the machine’s forming and cutting cycle, and the film has to track straight through a narrow former without wandering. Fill volumes are small, so dosing accuracy matters more proportionally than on a larger pack, and a slight variation that would be invisible in a pouch shows up as an underweight sachet. None of this is difficult to get right. All of it has to be specified rather than assumed.

Waste Compounds Fast on a Multi Lane Machine

On a single lane pouch line a specification error produces a manageable amount of scrap. On a multi lane sachet machine running at speed, the same error multiplies across every lane and every cycle, which changes the economics of getting it wrong.

Where Sachet and Stick Programs Fail

Web width that does not divide accurately across the lane count.
Pitch mismatched to the machine's forming and cutting cycle.
Film tracking off centre through a narrow former at speed.
Powder at the seal area causing leaks across multiple lanes at once.
Tear notch or laser score placed where the pack will not open cleanly.

Our Solutions

Web width calculated against your actual lane count and slit tolerance.
Pitch confirmed from the machine specification before plates are cut.
Film stiffness and slip specified for a narrow former at production speed.
Sealant chosen assuming a powder contaminated seal area.
Opening feature positioned and tested for a clean single handed tear.

Sachets, Cartons and the Outer Pack

Printed films and roll stock for sachet and stick machines, folding cartons for retail packs of sticks, corrugated shipping cartons, counter displays and labels. A stick pack almost never sells individually, so the carton around it is part of the specification.

What Goes Into a Sachet or Stick Specification

On sachets and stick packs, machine geometry dominates. The product decides barrier and sealant, and everything else comes from the filler.

Machine Geometry

Web width, lane count, pitch, core diameter and unwind direction taken directly from the filler rather than assumed.

Seal Configuration

Three side or four side seal, with sealant chosen for what your product deposits during a small volume fill.

Opening Feature

Tear notches or laser scoring positioned so the pack opens cleanly with one hand, which is the whole point of the format.

Barrier and Print

Laminate set from shelf-life claim, with digital print suiting sampling runs and conventional suiting core volume.

Powders and Liquids Want Different Films

A fine powder and a viscous liquid are opposite problems in the same format. Powders carry static, dust the seal area and cling to the former, so film slip properties and sealant choice both have to account for contamination and the fill has to be timed against dust settling. Liquids and gels put the emphasis on seal strength and burst resistance, since a small pack under pressure in transit will find the weakest point in a seal. Viscosity also affects fill speed, which affects how much dwell the seal gets. Add heat sensitive product and the window narrows again. We ask what the product is, its viscosity or particle size, the fill volume, the lane count and your sustained speed, and where the fill happens at a contract manufacturer we work from their machine details rather than yours.

Four Things We Confirm First

The list is short and skipping any of it produces waste at a rate this format does not forgive.

Lane Count and Web

The arithmetic that has to work

Web width divided across the lane count has to land within the machine’s tolerance, allowing for slit accuracy. This is arithmetic rather than judgement, and it is the most common failure point.

Pitch

Matching the machine cycle

Pitch has to match the forming and cutting cycle exactly. A small mismatch accumulates across a run and shows as inconsistent pack length and print position.

Product Form

Powder, granule, liquid or gel

Product form decides sealant, film slip and how much of a contamination problem the seal area has. Powders and liquids need genuinely different specifications in the same format.

Purpose

Retail dose or sampling

A core retail stick and a promotional sample sachet have different volumes, print needs and order patterns. Sampling favors digital print and shorter runs, which changes the plant choice.

Filler First, Then Film

We capture the machine geometry for sachets and stick packs before anything else, because that is what decides whether the order is usable.

Filler Specification Capture

We document lane count, web width, pitch, core, unwind direction, fill volume, seal configuration and your sustained operating speed.

Specify and Quote

We set barrier, sealant, film properties and opening feature around your product, then price through plants that hold tight slit and registration tolerance.

Trial and Supply

We prove a new structure on a trial quantity where the machine has not run it, then manage supply with delivery and brokerage handled.

On a multi lane machine at speed, a small specification error is not a small problem. It multiplies with every cycle.

Tolerance Is a Plant Selection Problem

We purchase from manufacturing partners and sell to you, so we can place tight tolerance work with plants that hold it rather than with whoever quoted first.

Plant Matched to Tolerance

Slit accuracy and registration vary between plants more than most buyers realize. On this format that difference decides whether a run is usable.

Machine Led Specification

We start from lane count, web and pitch rather than from a product brief, because the machine sets the constraints that cannot be negotiated.

Carton Included

Retail cartons, cases and counter displays for stick packs sourced in the same program, since sticks almost never sell individually.

Sampling and Core

Promotional sampling runs and core retail volume handled differently and priced accordingly rather than forced through one arrangement.

Doses, Portions and Sampling

The format exists to deliver one measured dose or portion, and the categories follow from that. Powdered supplements and drink mixes, instant coffee, tea and infusion powders, electrolytes, creamers, sugar and sweeteners, condiments, sauces and dressings, and single use personal care products all use it. Sampling is the other major use and it behaves like a different business, with short runs, many variants and print requirements that favor digital. Where the format really earns its place is trial, because a sachet is the cheapest way to put a product in someone’s hand. Brands running both a core retail stick line and an ongoing sampling program are usually better served treating them as two specifications rather than one, and the cartons, cases and displays around the retail line come from the same program either way.

What Our Clients Are Saying

Reliability that teams can measure.

As a small but growing brand, we struggled to find a packaging supplier who would take us seriously. AR not only welcomed us — they partnered with us. Their work with other startups showed in the quality of our packaging, and Daron went above and beyond, including helping our co-manufacturer optimize their equipment so our pouches came out perfect. We couldn’t ask for a more supportive, solution-focused partner.

Sachet and Stick Pack Questions

What do you need to quote sachets and stick packs?

The filler details first. Lane count, web width, pitch, core diameter, unwind direction, seal configuration and your sustained operating speed. Then the product, meaning whether it is a powder, granule, liquid or gel, its particle size or viscosity, the fill volume per pack and the shelf life you need to hold. Then whether this is core retail volume or a sampling program, since those price and print differently. With that information the specification is straightforward. Without the machine geometry, a quote can arrive perfectly made and unusable.

Why is web width such a problem on this format?

Because it has to divide accurately across the lane count, and slit accuracy at the plant has to be good enough that every lane lands within the machine’s tolerance. On a single lane pouch line a slight width variation is absorbed. On a multi lane sachet machine it puts some lanes out of specification while others run fine, which produces intermittent faults that are frustrating to diagnose. We calculate the width against your lane count including slit tolerance, and place the work with plants that can hold it, rather than treating width as a nominal figure.

Our powder keeps causing seal leaks. What can be done?

It is the most common failure in the format and it is manageable rather than inevitable. Fine powder carries static, dusts across the seal area during a fast small volume fill and sits between the film layers, creating channels that look sealed and fail testing. The variables are sealant choice, film slip and surface properties, jaw pressure, and the timing between fill and seal that lets dust settle. Because the machine runs multiple lanes, the fault often appears on some lanes and not others, which points to slit or tracking as well. We specify assuming contamination rather than a clean seal.

Can you supply the retail carton for our stick packs?

Yes, and it is usually necessary, because a stick pack rarely sells on its own. A retail pack of thirty sticks needs a folding carton dimensioned to the stick length and count, a corrugated case sized to the retail cartons, and often a counter display. Those are paperboard and corrugated purchases from different industries to the film. We purchase across all of them and sell to you as one program, so the stick dimensions, the carton and the case count are settled against each other rather than by three suppliers working from three assumptions.

Do you manufacture sachet film?

No. We purchase from manufacturing partners and sell to customers. On a tight tolerance format the benefit is concrete, because slit accuracy and print registration differ meaningfully between plants and we can place the work where the tolerance is genuinely held. We are also free to treat a sampling program and a core retail line as different sourcing problems, using a plant suited to short digital runs for one and a volume plant for the other, which a single converter quoting its own equipment cannot do.

Are sustainable options available in this format?

Less readily than in larger formats, and it is worth being direct about why. These structures are thin, the tolerances are tight and the seal has to be reliable at high speed across multiple lanes, which leaves little latitude for material substitution. Where a percentage of post-consumer recycled content can be introduced without compromising the seal or the tracking, we will specify it. On the retail carton and case around the sticks, recycled content and FSC-certified board are both available, and since that is most of the pack by weight it is where a documentable claim is easiest to make.
