What Is Sachet Packaging?
A sachet is a small sealed pouch designed for single-use or small-portion products. It is one of the most common flexible packaging formats for powder, seasoning, sauce, liquid, sugar and coffee products sold in individual servings. Custom sachet packaging can be produced as a premade three side seal pouch, or as roll film that runs on automatic VFFS or HFFS machines. Powder sachet packaging is widely used for milk powder, protein powder and instant drink mixes. Sauce sachet packaging covers ketchup, chili sauce, salad dressing and condiment portions. Liquid sachet packaging handles small liquid portions, gel products and liquid seasonings.
What Is Stick Pack Packaging?
A stick pack is a narrow, elongated single-serve flexible pack produced from roll film on dedicated stick pack machines. This format is particularly common for instant drink powder, coffee sticks, sugar sticks, creamer powder, supplement powder and seasoning powder. Stick pack packaging requires precise control over roll width, eye mark registration, film tension, sealing layer quality and cutting accuracy. The resulting pack is compact, easy to carry, and provides excellent portion control.

When to Choose Sachet Packaging
Sachet packaging is the right choice when your product benefits from a wider pack shape that provides more printable surface area for branding and product information. This format works well for powder, seasoning, sauce and small food portions where a flexible filling weight range is needed. If your product requires a tear notch or easy-open feature, sachets can accommodate these. You can start with premade three side seal pouches for lower equipment investment, or use roll film for higher-volume automatic production.
When to Choose Stick Pack Packaging
Stick pack packaging is the preferred choice when you need a narrow single-serve format optimized for portion control. Products like instant drink powder, coffee, sugar, creamer and supplement powder are well-suited. If you operate a high-speed automatic stick pack line, this format delivers efficient material usage and fast production speeds.\n\nWhen Not to Choose Stick Pack: Avoid if your product is too large or irregularly shaped for the narrow forming tube, needs wider branding area, has difficult filling characteristics for narrow format, needs zipper/spout/valve features, or if no suitable stick pack machine is available.\n\nWhen Not to Choose Sachet: Avoid if your product specifically requires long narrow single-serve dosing, you already have a fixed high-speed stick pack line, pouch width would waste material, or product presentation works better as a stick pack.\n\nThree Side Seal Pouch vs Roll Film: Premade three side seal pouches are finished ready-to-fill pouches sealed on three sides, suitable for small runs, samples, trial packs and powder/seasoning sachets. They lower initial equipment investment. Roll film feeds into automatic machines for continuous forming, filling, sealing and cutting. It requires machine-matched width, thickness, roll diameter, core size, eye mark and sealing layer. If no automatic machine, start with premade pouches. For high-volume automatic lines, roll film is more efficient.\n\nMaterial Structure Suggestions (starting points, not fixed solutions): PET/PE for general dry food, powder and small food sachets. BOPP/CPP for lightweight food packaging with good machinability. PET/VMPET/PE for improved moisture and light barrier. PET/AL/PE for higher barrier with aroma, moisture and oxygen protection. PA/PE for puncture resistance or flexibility needs. Paper/PE or Kraft laminated for natural look. Key considerations: powder needs moisture protection; coffee/sugar needs aroma and moisture barrier; sauce/liquid needs stronger sealing and inner layer compatibility; seasoning needs good barrier and sealing stability.\n\nApplication Table: Powder Sachet Packaging — milk powder, protein powder, instant drink, seasoning powder — focus on moisture barrier and sealing stability. Seasoning Sachet Packaging — salt, pepper, spice mix, sauce powder — focus on moisture resistance, aroma protection and easy tearing. Coffee Sugar Single Serve — coffee sticks, sugar sticks, creamer powder — focus on aroma, portion control and machine compatibility. Sauce Sachet Packaging — ketchup, chili sauce, salad dressing, condiment sauce — focus on sealing strength, inner layer and leakage risk control. Liquid Sachet Packaging — small liquid portions, gel products, liquid seasoning — structure checked per viscosity, filling weight, sterilization/storage. Single-Serve Snack Packaging — sample packs, trial packs, small food portions — choose based on pack shape, shelf display and cost.\n\nQuality Control Points: Sealing strength must hold through filling, transport and handling. Cutting accuracy critical for stick pack consistency. Eye mark accuracy essential for roll film registration. Film tension affects seal alignment and dimensions. Pouch size tolerance within spec. Moisture barrier matched to product sensitivity. Oxygen barrier for oxidation-sensitive products. Print registration across production run. Packing machine compatibility verified for buyer's specific model. Leakage risk management for sauce and liquid products.\n\nMachine Compatibility Checklist: Machine type (sachet / stick pack / VFFS / HFFS), roll width, film thickness, roll outer diameter, core size, eye mark position, sealing temperature range, cutting position, filling weight, packing speed, product flowability, forming size.\n\nSuggested Diagrams for Reference: 1.
