Product Overview
Sino Topway's polypropylene laminated woven bags are high-strength packaging solutions engineered for demanding applications such as animal feed, fertilizer, grain, flour, rice, sugar, and construction materials.
Each bag is crafted from woven polypropylene fabric reinforced with an outer laminated film-either BOPP (biaxially oriented polypropylene) or kraft paper-providing excellent moisture resistance, tear strength, and vivid print quality.
Unlike simple plain-woven sacks, our laminated bags combine structural integrity with premium branding, making them ideal for both bulk transportation and retail display in international markets.
Key Features & Material Options
- Laminated Structure: PP woven fabric bonded with BOPP film or kraft paper for superior moisture and dust protection.
- High-Quality Printing: Up to 10-color gravure printing on BOPP film for vibrant and detailed brand graphics.
- Durable Performance: Tear-resistant, UV-stabilized, and suitable for rough handling during transportation.
- Surface Options: Glossy or matte finish, available in transparent, semi-transparent, or fully opaque styles.
- Lamination Choice: One-side or both-side lamination for custom ventilation and print exposure.
- Closure Styles: Easy-open sewing, hot melt tape sealing, or valve-type filling options available.
- PE Liner Option: Inner PE liner or inserted film available for enhanced moisture control.
- Bottom Types: Block bottom for upright display or pillow-type for compact stacking.
Applications of Polypropylene Laminated Woven Bags
These laminated woven sacks are widely used in industrial and agricultural packaging, including:
- Grains & Seeds: Rice, corn, wheat, sorghum, soybeans, barley, and pulses.
- Animal Feed: Poultry feed, livestock feed, horse feed, and aqua feed.
- Fertilizer & Chemicals: Suitable for nitrogen, phosphate, potash, and granular chemicals.
- Flour, Sugar & Salt: Food-grade options available for dry ingredient storage.
- Construction Materials: Cement, sand, and powder products requiring leak-proof sealing.
- Charcoal & Minerals: Anti-dust and high-strength bags for retail charcoal packaging.
These bags are widely exported to Canada, Mexico, the European Union, South America, Africa, and the Middle East-regions that demand both durability and strong shelf presence.
Manufacturing Process
- Woven Fabric Extrusion & Weaving – High-density polypropylene tapes are extruded and woven into a durable base fabric.
- Printing on Film – The BOPP or paper layer is printed first using gravure printing for sharp, detailed images.
- Lamination – Printed film is laminated onto the woven fabric for a composite moisture-resistant structure.
- Cutting & Forming – The laminated fabric is cut to the required size and shape.
- Sewing or Sealing – Bags are sewn or heat-sealed, with options for easy-open sewing, valve filling, or hot melt tape sealing.
- Block Bottom Formation – A pre-laminated rectangle is glued to the base for a flat, stable bottom.
- Inspection & Packing – Final quality checks ensure consistent print quality, strength, and lamination before shipment.
