Start with the product formula
The formula decides the pack. A water-based lotion, a silicone serum, an alcohol-heavy toner and a powder blush each attack a pouch differently. Alcohol and fragrance can swell or soften some sealants. Essential oils can migrate through polyethylene. Powders need a stiff structure that stands and resists creasing. Before choosing a laminate, list the ingredients that touch the sealant layer, the pH range, and whether the product is hot-filled.
Water activity and oil content matter too. High-oil formulas can weaken some adhesives over time. High-water formulas need a strong moisture barrier to stop weight loss. If the product contains solvents, test the seal strength after two weeks at 40°C. A supplier with BRC-certified factories can run these checks on the actual laminate, not just on a data sheet.
Match the laminate to the barrier need
Barrier is not one number. It is a set of rates: water vapour transmission, oxygen transmission, and light transmission. PET/AL/PE gives a strong all-round barrier for creams and serums that are sensitive to oxygen and light. PET/NY/PE is a good choice when you need puncture resistance and a clear pack, for example for sample sachets or travel sizes. Kraft paper laminates suit brands that want a natural look, but they offer a lower moisture barrier than foil structures.
For refill pouches, consider mono-material PE or PP recyclable structures. They are designed to fit existing recycling streams where collection exists. PLA/PBS compostable options are available for brands that meet industrial composting rules. Degradable options also exist, but they are not the same as compostable and should not be mixed up in claims. Always check the barrier data for the exact gauge you plan to use.
Choose the format for filling and use
The filling line often limits the format. A stand up pouch with a zipper is easy to fill from the top, but a spout pouch needs a spout fitment and a cap, which adds a filling step. A flat bottom pouch stands well on shelf and holds more volume for the same footprint. A three-side-seal pouch is simple and low cost, but it does not stand. A side gusset bag works for larger sizes, such as 1 kg masks or bath salts.
Think about how the user opens and closes the pack. A tear notch helps a first open. A zipper helps repeated use. A spout and cap suit liquids and gels that are poured or squeezed. A one-way degassing valve is for products that release gas, not for standard creams. A hang hole helps retail display. A window can show the product, but it reduces the barrier area, so check the shelf life.
Understand what drives the price
Four things move the unit price: print method, material structure, order quantity and add-ons. Rotogravure printing uses engraved cylinders, so it has a higher setup cost but a lower unit cost at large volumes. Digital printing has no cylinder cost, which makes it suitable for short runs and frequent artwork changes. Flexographic printing sits between the two for some designs.
Material is the next driver. Foil laminates cost more than clear PE structures. Recyclable mono-material PE often costs more than a standard mixed laminate because it needs a different sealant and sometimes a different print surface. Add-ons add cost and lead time: a spout and cap, a zipper, a valve or a handle each add a component and a step. Minimum order quantity also affects price. Digital print can start from 100 pcs for pouches or 10 kg for film. Rotogravure starts from 10,000 pcs or 200 kg. Lead time is 10-15 working days for digital after artwork approval, and 20-25 working days for rotogravure.
Sustainability claims need evidence
Recyclable, compostable and degradable are three different claims. A mono-material PE or PP pouch can be labelled recyclable only if the local collection system accepts it. A PLA/PBS pouch can be labelled compostable only if it meets the relevant industrial composting standard. Degradable means the material breaks down over time, but it may not return to soil safely. Do not use these words interchangeably.
Also consider the full pack. A recyclable pouch with a non-recyclable spout, valve or zipper may not pass a recyclability assessment. If the cap or fitment is a different polymer, the pack may need to be separated before recycling. For refill formats, the best gain is often less material and less weight, not a new logo. Keep the claim specific: state the material, the standard, and the region where the claim applies.
Avoid common sourcing mistakes
Most problems start before the first order. Common mistakes include:
Choosing a laminate from a data sheet without testing the actual product.
Forgetting that the sealant layer must be compatible with the filling temperature.
Ordering a spout pouch without checking the filling line can handle the fitment.
Using a window or a clear patch without rechecking the shelf life.
Assuming a stock pouch size will fit a new fill weight.
Leaving artwork approval to the last week before a launch.
A short pre-production sample run catches most of these issues. It also confirms the print colour, the seal strength and the opening force. For short runs, digital print keeps the tooling cost low. For large runs, rotogravure gives a lower unit cost. Free stock pouch samples are available; the customer pays courier only.
