sachet

The choice of material depends entirely on the contents. For food-grade products, ensure the use of BPA-free, FDA-approved plastics or aluminum foil laminates to provide a high moisture and oxygen barrier. For fragrance or desiccant sachets, breathable materials like non-woven fabrics or Tyvek are essential to allow scent release or moisture absorption while preventing leakage of internal granules.

To prevent leakage and oxidation, prioritize suppliers using advanced heat-sealing technology with a seal strength of at least 15N/15mm. For liquid or powder products, request leakage tests (vacuum method) and ensure the film thickness is appropriate (typically 60-120 microns) to maintain product freshness and prevent punctures during transit.

Depending on your target market, you must verify ISO 22000 for food safety, REACH for chemical content in fragrance sachets, and CE marking if applicable. If you are targeting eco-conscious markets, look for GRS (Global Recycled Standard) or biodegradable certifications (EN 13432) to ensure the packaging meets local environmental regulations.

Yes, most professional suppliers on Made-in-China.com offer OEM/ODM services. You can customize the printing (Gravure or Digital), shape (e.g., die-cut irregular shapes), and features like tear notches, zippers, or euro-holes for hanging displays. Ensure you provide high-resolution AI or PDF design files to maintain print clarity.

Always request a pre-production sample before the full run. For bulk orders, hire a third-party inspection service to conduct a Random Sampling Inspection (AQL 2.5/4.0) focusing on seal strength, print alignment, and quantity accuracy. Using Secured Trading Services on Made-in-China.com can also protect your payment until the goods pass inspection.

Sachet production is highly volume-dependent due to machine setup costs and plate-making fees. To lower the unit price, aim for orders above 10,000 to 50,000 units. If you are a startup, negotiate a higher unit price in exchange for a lower MOQ for the first order, with a written agreement that the plate fees will be refunded once a certain cumulative volume is reached.

Sachets are lightweight but can be easily crushed. Ensure the supplier uses 5-layer corrugated export cartons and inner polybag lining to protect against moisture during sea freight. For liquid-filled sachets, specify reinforced palletization to prevent bottom-layer bursting due to vertical pressure during long-distance shipping.

Verify the correct HS Code (e.g., 392321 for plastic bags or 330749 for scented sachets) to calculate accurate import duties. Be aware of anti-plastic legislations in regions like the EU, which may require specific recycling logos or 'Plastic in Product' warnings to be printed on the sachet to avoid customs clearance delays.
