Packaging Materials Explained

Packaging material affects protection, weight, surface finish, printing, storage, food-contact suitability, and end-of-life options.

Material Types at a Glance

Kraft paper

Natural brown paper known for tactile fiber texture, matte finish, and common use in wraps, sleeves, and bags.

Paperboard

Thicker paper-based board used for folding cartons, sleeves, cards, and printed retail packaging.

Corrugated fiberboard

Layered board with fluting that improves cushioning, stacking strength, and shipping protection.

Molded fiber

Formed pulp material used for trays, inserts, cushioning, and protective shapes.

Plastic film

Flexible material used where transparency, sealing, moisture resistance, or lightweight wrapping is required.

Bioplastic

Plant-based or compostability-linked plastic category that still requires careful end-of-life context.

Recycled paper

Recovered-fiber paper useful for understanding source, texture, performance trade-offs, and recovery claims.

Study food-contact suitability, grease or moisture resistance, coatings, and storage conditions.

Compare print surface, stiffness, folding behavior, color accuracy, and tactile feel.

Learn how corrugated grade, box size, stacking, humidity, and handling affect performance.

Review material source, coating, recyclability, composting context, and realistic disposal options.

Strength and stiffness

Affects stacking, fold quality, crushing resistance, and handling feel.

Surface and print behavior

Matte, glossy, coated, uncoated, and textured surfaces all affect ink and visual finish.

Barrier requirement

Moisture, oil, oxygen, aroma, and heat exposure may require coating, lining, or a different material family.

Food-contact suitability

Food packaging requires attention to whether the material, coating, ink, and use condition are suitable for direct or indirect contact.

End-of-life route

Recyclable, compostable, reusable, and biodegradable claims depend on material composition and local systems.
