Recommended 40kg Biomass Pellet Bag Specification
This is the practical specification that matches your preferred biomass pellet buyer requirement. Use it as a starting point, then adjust based on pellet density, filling machine, stacking height and delivery route.
| Specification | Preferred Option | Buyer Note |
|---|---|---|
| Application | Biomass pellet, biofuel pellet, boiler pellet packing | Suitable for industrial fuel pellet suppliers and dealers. |
| Fill weight | 40kg | Good middle load for handling, transport and warehouse stacking. |
| Pellet size | 6 mm to 9 mm pellets | Useful for common pellet diameters. Confirm actual bulk density before final size. |
| Bag size | 22x32 inches | Preferred size direction for 40kg pellet packing. Final sample test recommended. |
| Bag weight | 77 gram approximate target | Useful for buyer costing and fabric comparison. Final weight can vary by fabric, lamination, liner and stitching. |
| Strength | 48 kgs target strength | Suitable strength direction for 40kg pellet handling when fabric and stitching are made correctly. |
| Fabric | 3.5 gram fabric option | Local buyer term. Confirm actual GSM, tape denier, bag weight and strength during sampling. |
| Lamination | Milky lamination | Also searched as milkey lamination. Helps surface protection and cleaner appearance. |
| Liner | Optional natural or milky PE liner | Recommended for monsoon, long storage and valuable pellet products. |
| Printing | Plain, flexo printed or BOPP printed | Use for brand name, fuel grade, net weight, pellet size and contact details. |
| Stitching | Strong bottom stitch, optional double stitch | Important for lifting, stacking and transport safety. |
Why 40kg Packing Works for Biomass Pellets
A 40kg biomass pellet bag can be easier to handle than a 50kg bag and more cost-effective than smaller 20kg or 25kg packs. For manufacturers selling to industrial users, boilers and distributors, 40kg often gives a practical balance between bag cost, labor handling and transport efficiency.
Better handling
40kg bags reduce lifting stress compared with heavier 50kg packaging.
Good bulk value
More economical per kg than small retail-style bags for industrial buyers.
Warehouse friendly
Works well for stacking when fabric, stitching and palletizing are selected correctly.
Moisture-Proof Protection for Valuable Biomass Pellets
Biomass pellets can lose quality when they absorb moisture. The product may swell, break, create dust or become difficult to burn efficiently. For valuable products, bag protection should be stronger than only plain PP woven fabric.
PP Fabric
Select fabric strength based on 40kg load and handling.
Milky Lamination
Add a surface barrier and clean white appearance.
PE Liner
Use liner for monsoon, export or longer storage.
Stitching
Strong bottom stitching reduces leakage risk.
Pallet Cover
Protect stacked bags from warehouse humidity and dust.
Practical note: Moisture-proof does not mean the bag should be kept in rain or water. Best protection comes from lamination, liner, correct stitching, pallet cover and dry warehouse storage together.
Printing Options for Biomass Pellet Bags
Printed biomass pellet bags help buyers identify fuel grade, pellet size, bag weight and supplier contact details. For factories and distributors, clean printing also makes the product look more professional.
| Printing Option | Best For | What to Print |
|---|---|---|
| Plain milky laminated bag | Cost-focused industrial supply | Optional sticker or batch marking. |
| One-color flexo print | Regular brand identification | Company name, product name, 40kg, pellet size and phone number. |
| Two or three-color flexo print | Dealer and distributor supply | Logo, boiler fuel grade, moisture warning and handling instruction. |
| BOPP printed bag | Premium product and export supply | Full artwork, product photo, fuel grade, net weight and contact details. |
