BiSheng Packaging, a professional flexible packaging manufacturer focused on export-ready solutions, today launched its latest innovation: wicket bags equipped with iron wire & cardboard header (paperboard card). Designed to perfectly fit automatic filling machines, this new bag format addresses the growing demand for efficient, sustainable-ready, and compliant food packaging in supermarkets and the prepared meal (ready-to-eat) sector.
Combining the rigidity of a paperboard header with the convenience of wicket wire (iron wire) stacking, BiSheng’s new packaging allows seamless integration into high-speed vertical and horizontal form-fill-seal lines. The wicket iron wire securely holds stacks of bags, while the cardboard header provides excellent stiffness for automatic dispensing — significantly reducing downtime and improving filling accuracy for food processors and co-packers.
✔ Key product highlights:
• Wicket wire (iron bar) design – stacks of bags load directly onto automatic filling wicket pegs.
• Cardboard header (paperboard card) – reinforced top for smooth mechanical denesting.
• FDA & EU food-grade compliant – low solvent, food-contact safe materials.
• Superior sealing performance – ideal for ready meals, frozen foods, and supermarket retail.
• Versatile application – prepared dishes, pre-cooked meals, snacks, and private-label retail.
“Supermarkets and prepared-food brands are increasingly moving toward automation-ready packaging that does not compromise on food safety or efficiency,” said the Product Director at BiSheng Packaging. “Our wicket bags with cardboard header are designed to run flawlessly on fully automatic filling equipment, while the low-solvent, high-seal-strength material meets the strictest EU and FDA standards.”
Engineered for Performance & Compliance
BiSheng’s new wicket bag series uses low-solvent-residue inks and adhesives, fully compliant with EU 10/2011 and FDA 21 CFR. The cardboard header is made from food-grade paperboard, and the wicket iron wire is rust-proof treated. The bag body delivers:
• Excellent heat seal strength – prevents leakage during transport and shelf display.
• High puncture resistance – suitable for bone-in or rigid frozen products.
• Outstanding barrier properties (moisture/oxygen) – extends shelf life for prepared meals.
• Clean peel or easy-tear options – enhancing consumer convenience.
These wicket bags are available in multiple sizes, custom printed with high-definition gravure (rotogravure) up to 10 colors, and can be produced with clear windows or matte finishes. The cardboard header can carry branding, barcode, cooking instructions, or nutritional information — replacing separate labels and reducing packaging waste.
Wide Applications: Supermarket Retail & Prepared Meals
The new packaging is universal for both supermarket retail and ready-to-eat (RTE) food industry. Typical applications include:
• Frozen ready meals (pasta, rice, stir-fry kits)
• Pre-cooked meat and poultry products
• Fresh-cut vegetables and fruit pouches
• Private-label supermarket convenience foods
• Meal kit components and side dishes
Thanks to the wicket & cardboard header design, filling lines can operate at speeds up to 80–120 bags per minute with negligible jamming. The low-solvent composition also ensures no off-odors or migration, making it safe for hot-fill and pasteurization processes.
