The differences at a glance
Terminology can overlap between suppliers. A sample or dimensioned drawing is more precise than the pack name alone.
| Feature | Stick pack | Sachet |
|---|---|---|
| Shape | Long and narrow. | Usually a wider rectangle or square. |
| Seal layout | Commonly a back seam and two end seals. | Commonly three or four side seals; check the drawing. |
| Opening | Test the end tear and the pour or squeeze action. | Test tear position, opening width and emptying. |
| Design | Long, narrow front face. | Wider front face for artwork and grouping. |
Can powder or liquid use either format?
The format name does not select the dosing system. For a powder, discuss flow, dust and the space needed for the target portion. For a liquid or paste, discuss temperature, viscosity and how filling stops without contaminating the seal. Check the intended opening with the actual product and film. Neither shape alone establishes shelf life, filling accuracy or production speed.
What should you prepare before choosing a machine?
Send a front-and-back photo or drawing of the desired pack, its width and length, the amount per pack, product details and available film information. Add your required output and whether packs will be counted or cartoned. If the format is still open, share both options. Sample testing can then compare filling, sealing and opening under agreed conditions before a configuration is selected.
