Introduction

Heavy Duty BIB Liners are designed for applications where the bag will face extreme mechanical stress—such as bulk handling, filling high-viscosity products, or containing abrasive chemicals. Suzhou Jingle Packaging reinforces these liners using specialized, high-gauge polymers (e.g., 150 micrometer}+ PE or laminated Nylon layers) to boost puncture and tear resistance. The seams are over-welded to prevent failure under extreme pressure, guaranteeing product safety throughout a challenging logistics chain.

This is the preferred liner for industrial chemicals, heavy purees, and long-distance bulk transport.

Specification**

Film Thickness	High gauge (e.g., 150 micrometer} to 250 micrometer})
Material Type	Co-extruded PE with Nylon or PA for structural strength
Puncture Resistance	Superior (Tested with sharp impact and drop tests)
Sealing Method	Double or triple reinforced thermal welding
Volume Range	10L up to 1000L (IBC Liner)

Logistics & Global Compatibility

Freight Reliability: Preferred by logistics companies for products shipped under potentially rough handling conditions.
Compliance: Structural integrity assists in meeting bulk UN packaging performance tests for certain non-hazardous goods.
Universal Fit: Available to fit standard global drum and IBC formats.
Manufacturing Control: Strict QC measures ensure consistent film gauge and weld strength across all batches.

FAQ

Q: How is the puncture resistance measured?
A: Using standard tests like the Dart Drop Test or specific probe puncture tests that measure the force required to breach the film.

Q: Is a heavy-duty bag required for wine?
A: Generally not, unless the wine is being shipped in bulk 220L drums where the high payload demands a more durable material for safety.

Q: Does the extra thickness affect the filling process?
A: The film is thicker but still flexible and easily handled by standard bulk fillers. It does not negatively impact the filling speed or accuracy.

Advantages

Damage Prevention: Minimizes the risk of costly leaks and spills from puncture during handling and transit.
High Pressure Tolerance: Withstands the intense pressure generated by filling or discharging highly viscous liquids.
Enhanced Safety: Provides an extra layer of containment for chemicals or high-value food products.
Long-Term Integrity: Robust construction prevents material degradation or stress cracking during extended storage periods.

Application

Viscous Pastes: Containing tomato paste, thick fruit purees, or industrial resins.
Heavy Liquids: Bulk packaging of high-density materials like liquid chalk or pigments.
Abrasive Chemicals: Detergents with suspended solids or industrial cleaners.
Frozen Transport: Used in conjunction with low-temperature PE for added impact resistance when frozen.
