Cardboard-Header Wicket Bags Iron-Wire Hanger Design · Optimized for Fully Automatic Filling Lines
Core Design & Structural Advantages
Automatic packaging film refers to a packaging material used in packaging and packing, which has a stretching effect. When using automatic packaging film, it can save materials, labor, and time. Automatic packaging film is commonly used in packaging papermaking, logistics, chemical industry, plastic raw materials, building materials, food, glass, and other fields.
The material type is also consistent with plastic packaging bags, commonly including PVC shrink film roll film, OPP roll film, PE roll film, PET protective film, composite roll film, etc. Roll film is applied to automatic packaging machines, such as common bagged shampoos and some wet wipes, which use this packaging mode. The cost of using roll film packaging is relatively low, but it requires a matching automatic packaging machine.
Key Applications – Supermarket Retail & Prepared Meals
These wicket bags are purpose-built for high-throughput environments, bridging the gap between efficient automation and consumer-friendly retail presentation. Typical end-uses include:
Frozen ready-meals (pasta/rice/stir-fry bowls) Pre-cooked sous-vide & roasted meats Fresh-cut produce & salad kits Private-label convenience foods (retail chains) RTE meal components & side dishes Pet food (wet & semi moist formulas) Snacks with point-of-sale hanging display
The flat cardboard header acts as a stable “branding billboard” on supermarket shelves, while the wicket system supports fully automated bag handling — making it the ideal choice for co- and large-scale food manufacturers that run multiple SKUs on the same line.
Technical Specifications & Performance Data
Film Structure (customisable)
Multi-layer co-extruded films: PE / PA / EVOH / Aluminium foil / Metallised PET. Thickness range 60–150 μm depending on barrier and mechanical requirements.
Cardboard Header
Solid bleached sulfate (SBS) paperboard, 300–450 gsm; PE-coated optional for moisture resistance. Printable with up to 6 colours (CMYK + spot).
Wicket Wire
Galvanised low-carbon steel wire, diameter 2.0 mm / 2.5 mm (±0.05 mm). Tensile strength ≥350 N/mm². Hole spacing customised (typically 38–50 mm centre-to-centre).
Heat Seal Strength
≥45 N/15mm (standard PE sealant); ≥55 N/15mm with high-performance sealant layers. Seal initiation temperature: 110°C–140°C.
Total Solvent Residue
≤5 mg/m² (measured by GC-MS); benzene, toluene, xylene: not detected. Compliant with FDA 21 CFR 175.300 and EU 10/2011 migration limits.
Oxygen Transmission Rate (OTR)
As low as ≤1 cc/(m²·24h·atm) with EVOH or AlOx barrier layers; standard structures ≤15 cc/(m²·24h·atm).
Water Vapour Transmission Rate (WVTR)
≤1.5 g/(m²·24h) (high barrier); ≤8 g/(m²·24h) (standard).
Puncture & Burst Resistance
Puncture resistance ≥10 N (ASTM F1306); burst strength ≥35 psi (internal pressure test) — suitable for frozen bone-in products and shelf-stable retort applications.
Operational Temperature Range
-40°C to +100°C (for freeze-thaw cycles and hot-fill up to 95°C).
Quality Assurance & Process Control
BiSheng Packaging implements a full-stage KPI monitoring system across film extrusion, gravure printing, lamination, curing, and wicket-assembly processes. Every production batch undergoes:
●In-process inspection: Automated thickness scanning, colour difference (ΔE ≤1.5), and coating weight verification.
●Solvent residue analysis: Gas chromatography testing for every printing/laminating batch.
●Seal integrity testing: Burst test, vacuum leak test (0.08 MPa for 30s), and peel strength measurement.
●Wicket alignment & hole accuracy: ±0.3 mm hole-position tolerance to ensure perfect compatibility with filling machine pegs.
We operate under ISO 22000:2018, BRCGS Packaging Materials (Grade AA), and FSSC 22000 frameworks. Full traceability from raw material lot to finished wicket-stack is maintained for all export orders.
Customisation & Operational Efficiency
Beyond standard specifications, BiSheng offers extensive customisation to match your specific filling equipment and product requirements:
●Flexible sizing: Bag widths from 100 mm to 450 mm, lengths from 150 mm to 600 mm.
●High-definition gravure printing: Up to 10 colours with matte/gloss varnish, holographic effects, and tactile coatings.
●Special header features: Euroslot, round hole, or custom-shaped hanger perforations; tear-notch integration for easy opening.
●Pre-inserted wicket wire: Bags delivered with wires already threaded, ready for immediate loading onto your filling line — reducing setup time by up to 30%.
●Recyclable options: Mono-material PE structures combined with paperboard headers for improved end-of-life recyclability (design-for-recycling).
We support on-site machine trials with sample bags to verify denesting, opening, filling, and sealing performance before full-scale production.
