Carton Liners

Wholesale Carton Liners for Australian Businesses

Carton liners are oversized poly bags that sit inside a corrugated carton to create a barrier between the product and the board. They protect contents from moisture, dust and contamination, and keep the carton itself clean for reuse. Premium Packaging supplies carton liners and drum liners in wholesale and bulk quantities to businesses across food production, manufacturing, export and warehousing, delivered Australia-wide from our Sydney base.

What Carton Liners Are

A carton liner is a large poly bag sized to fit inside a shipping carton, bin or drum. Made from durable polyethylene, it lines the interior so the product never touches the board directly. Food-grade liners suit direct contact with food products, while general-purpose liners protect non-food goods during storage and transit. Drum liners perform the same role inside drums and large containers, keeping bulk contents sealed and protected.

Why Businesses Use Carton Liners

A liner adds a protective barrier without changing your existing carton setup. It keeps moisture, dust and airborne contamination away from the product, which matters most for food, powders, granules and moisture-sensitive goods. Because the carton stays clean, it can be reused across more cycles, and contents stay contained even if the outer board is knocked or scuffed. Liners also pair with foam, bubble wrap and other protective packaging when goods need both a barrier and cushioning.

Common Applications

• Food production and food service. Food-grade liners for bulk ingredients, produce and packaged food where hygiene and direct-contact safety are required.
• Export and freight. A moisture and contamination barrier for goods travelling long distances or through humid conditions.
• Manufacturing and bulk goods. Lining cartons, bins and drums for powders, granules, components and industrial materials.
• Textiles and apparel. Keeping fabric and finished garments clean and dry through storage and distribution.
• Electronics and moisture-sensitive goods. An added barrier against moisture and dust for sensitive products.
• Long-term storage. Sealing contents inside the carton to protect them over extended storage periods.

Built for Commercial Packing Lines

On a busy packing line, a carton liner adds protection in a single step: the liner sits in the carton, the product is packed inside it, and the top is folded over before the carton is sealed. Because liners are sized to standard cartons, they fit the workflow your team already runs, and they arrive consistent every time so packers get the same result on every carton. For food and export operations where a barrier is not optional, keeping liners in stock protects both the product and your compliance requirements.

Choosing the Right Carton Liner

Grade. Choose food-grade liners for direct food contact and general-purpose liners for non-food goods.

Size. Match the liner to your carton, bin or drum so it lines the base and sides with enough at the top to fold over and close.

Gauge. Heavier gauges give greater puncture resistance for sharp, heavy or abrasive contents, while lighter gauges suit lighter goods. If you are unsure, our team can recommend a liner based on your carton size and what you are packing.

Complete Your Packing Supply

Carton liners work alongside the cartons and protective materials most operations reorder together. Line your cardboard boxes and cartons, add protective packaging or bubble wrap for fragile contents, and stock bin liners and plain poly bags for wider facility use.
