| Uncoated kraft paperboard | No added barrier, or a separate liner | Paperboard can absorb oil and moisture. It is generally better for dry foods than for wet, greasy, or saucy meals. | Sandwiches, bakery items, dry snacks, and foods served with a separate wrap or liner | Paper recovery depends on local collection rules and whether the container is clean and dry. Food and grease can affect acceptance. | Board strength, food-contact suitability, closure design, and whether a liner is required for the intended food |
| Kraft paperboard with a polyethylene (PE) lining | PE lining on the food-contact side; some formats use a lining on both sides | Provides a moisture barrier and can improve resistance to grease and leakage. Performance depends on the lining and container construction. | Hot or cold meals, saucy foods, and some oily foods, subject to supplier testing | The plastic lining can make paper recycling more difficult. Acceptance varies by local recycling systems and processing equipment. | Which surfaces are lined, heat-use guidance, leak resistance, and local recycling acceptance |
| Paperboard with a dispersion or water-based barrier coating | Coating applied to the paper surface for grease, moisture, or both | Can provide a barrier without a conventional PE film, but the level of protection varies by coating, application, and food conditions. | Bakery products, snacks, and selected greasy or moist foods when the coating is specified for that use | Some products may be compatible with paper recycling, but recyclability is not guaranteed by the coating type alone. Local mill acceptance matters. | Barrier test results, food-contact compliance, coating coverage, and documented recycling or composting claims |
| Paperboard with a PLA lining | Polylactic acid (PLA) bioplastic lining | Can provide a moisture barrier. Heat tolerance and performance vary by product; confirm suitability for hot foods and filling conditions. | Selected cold or warm foods and beverages where the supplier confirms the container’s intended use | PLA-lined packaging is not automatically home-compostable or recyclable with ordinary paper. Industrial composting requires suitable facilities and local acceptance. | Maximum use conditions, lining details, certification scope, and whether a local industrial composting program accepts the item |
| Molded fiber or pulp container | Uncoated fiber, a surface treatment, or a separate lining | Rigid molded shapes can protect food, but untreated fiber may absorb liquids and oils. Barrier performance depends on the finish. | Bowls, clamshell meals, and foods where a molded shape is useful; use a verified barrier for wet or greasy foods | Disposal options depend on coatings, food contamination, and local paper or composting rules. Do not assume all molded-fiber items are compostable. | Leak and grease testing, lid fit, stackability, temperature guidance, and disposal documentation |
| Paper container with a separate insert or liner | Removable paper, grease-resistant paper, or another specified food-contact liner | A separate liner can help protect the outer container, but it adds a component and may not prevent leakage unless designed for that purpose. | Greasy baked goods, fried foods, and mixed menus where a removable liner is practical | Separating components may improve sorting only where local systems accept each material. Food residue can still affect disposal options. | Liner material, food-contact suitability, fit, grease resistance, and clear separation instructions for customers |
