Competitors may boast about “eco-friendly” materials, but most insulated packaging suppliers still rely on plastic containing fillers or no-value foam cores. Our insulated box liners? All paper core. All recyclable. All proven.
CelluLiner box liners can widthstand the humidity and moisture that comes from frozen shipping delivery unlike most cellulose-based insulated box liners.
CelluLiner box liners and pouches can be efficiently flat-packed when not in use, resulting in substantial savings in storage and shipping costs.
Need to extend time-in-transit? Optimize for specific payloads? We’ll engineer a liner to your specs, not just our convenience.
Our liners consistently hold desired temperatures through extended transit times, backed by lab-tested ISTA profiles.
No waiting on overseas supply chains or getting stuck behind giant MOQs. We keep it lean and local.
CelluLiner’s 100% Paper Insulated Packaging delivers high-performance temperature protection using a fully paper-based construction. Its multi-layered paper insulation contains thousands of microscopic air pockets that help slow heat transfer, while the entire liner can be flattened and placed in curbside recycling after use. It is an ideal choice for businesses looking for effective cold-chain protection with a truly recyclable, plastic-free insulation solution.
For applications where additional moisture protection is important, CelluLiner is also available with a recyclable plastic outer covering. This configuration combines the high-performance paper insulation core with a recyclable plastic shell, providing reliable temperature control while adding a waterproof exterior and clean, professional appearance.
