“To many people packaging is just a bag. To us it is a craft — bags are all we make, and we make them properly.”

Chemical & Fertiliser Valve Bags
A white PP woven valve sack for titanium dioxide, zirconium silicate, pigments and blended fertiliser. Virgin woven fabric is film-laminated into a smooth, matte-white face — not a paper sack, so it will not tear on a wet pallet, and not a plain sack, because the face still takes a crisp print of product grade, standard code and net weight.
Supplied by Wenzhou Huishen Plastic Industry Co., Ltd. Sack size, fabric weight, lamination and print are made to order — commonly 25 kg for pigment powders and 40 kg for mineral fillers, with a self-sealing valve for dust-free filling on automatic lines.
- ✔ Virgin PP woven + PE film — clean, high-strength shell with a moisture-resistant face
- ✔ Smooth white print face — grade codes, standard references and net weight print sharply
- ✔ Self-sealing valve — fine chemical powders fill and close without dust
- ✔ 25–40 kg fills — one construction covers pigment sacks and mineral filler sacks
