Polywrap manufactures carton liners designed to protect packed contents from air, moisture, dust, dirt, and leakage-related contamination, produced from its fully integrated Victorian facility covering extrusion, printing, and conversion in-house. Carton liners are available in both generic and fully customised formats, sized to match specific box configurations rather than forcing businesses to adapt their packing process around a limited standard range. This flexibility is backed by Polywrap’s in-house manufacturing plant and team of technical experts, who work directly with clients to determine the right liner dimensions, thickness, and material for their particular packing application. Made from lightweight yet durable recyclable material, Polywrap’s carton liners are suited to a wide variety of contents across retail and wholesale packing environments, from food and agricultural goods through to general commercial products. Liners are available in tint or natural colour form, with thickness measured in micron to suit different levels of protection required, whether that’s a light moisture barrier or a more robust liner for longer transport and storage periods. Because carton liners are produced alongside Polywrap’s broader film range rather than through a separate outsourced process, businesses benefit from consistent quality and the ability to request adjustments without working through multiple suppliers. This matters particularly for companies packing perishable or sensitive goods, where inconsistent liner quality can directly affect product condition on arrival. With over 30 years of manufacturing experience, Polywrap’s technical team can advise on the right liner specification for a given carton size and content type, helping businesses avoid both under-protection and unnecessary material cost. Orders can be placed by calling Polywrap directly or through the company’s online order form.
