A Complete Guide to Sustainable Packaging Liner Materials

Paper-Based Materials:

Cardboard and Corrugated Cardboard
Corrugated cardboard is often considered the preferred sustainable packaging material because it is paper-based and sourced from renewable resources—trees. It usually has at least two layers, one flat and one wavy, with most packaging using three layers, where the corrugated core is sandwiched between two flat paper layers. This multi-layer structure gives corrugated cardboard excellent durability, effectively protecting products and absorbing shocks. Additionally, it is highly recyclable, cost-effective, and very flexible in design, customizable to various product shapes. From e-commerce shipping to retail packaging, corrugated cardboard liners are widely used across various industries and product types.

Paperboard
Paperboard is another sustainable material for packaging liners. Although not as thick as corrugated cardboard, it still enhances product display and serves as an eco-friendly alternative for items that don’t need heavy protection. Due to its thinner nature, paperboard does not significantly add to the overall weight of the packaging. Like corrugated cardboard, paperboard is also flexible and versatile, adapting to any product shape. Therefore, for lighter items that focus on product aesthetics, paperboard liners are a good sustainable choice.

Molded Pulp (including Bamboo and Sugarcane Pulp)
Molded pulp liners are primarily made from recycled paper and paperboard, making them a popular sustainable material for customized packaging. Recycled paper undergoes processes such as dry or wet pressing and is then molded into new shapes as packaging liners. The advantage of molded pulp is that it can be shaped according to the exact dimensions of the product for a perfect fit. Made from recycled materials, molded pulp liners are biodegradable and compostable, which helps enhance a brand’s eco-friendly image. Additionally, bamboo pulp and sugarcane pulp are increasingly valued as sustainable alternatives due to their renewability and rapid growth. Wet-pressed molded pulp also offers a smooth surface and excellent protection, making it suitable for higher-end products.

Chipboard
If a stronger material is needed than corrugated cardboard, chipboard liners are a suitable choice. Chipboard is made from reinforced paperboard and is ideal for heavier items that require robust, durable protection. It also gives packaging a more premium and luxurious appearance. While some chipboard is made from virgin pulp, there are suppliers offering recycled options to maintain sustainability. Therefore, for products needing additional strength and a high-end look, recycled chipboard liners can be a sustainable choice.

Plant-Based Alternatives:

Mushroom Packaging
Mushroom packaging is an innovative and eco-friendly choice that combines mycelium with agricultural waste. The mushroom roots grow and bind with materials like hemp fibers, creating a compostable and moldable packaging liner. Mushroom packaging offers excellent protection and can serve as an alternative to styrofoam. Although suppliers for this material may be few, it represents a promising sustainable packaging solution.

Seaweed Packaging
Seaweed, a biodegradable and even edible material, shows great potential in sustainable packaging. It grows quickly and requires minimal resources, making it suitable for various packaging needs. Although there are challenges in large-scale production and consistent quality, seaweed packaging remains a highly promising eco-friendly alternative.

Recycled and Bio-Based Plastics:

Recycled Plastics (e.g., rPET)
Recycled plastics, such as PET, help reduce the demand for virgin resources. Various types of recycled plastics are used in packaging. However, it is important to note that the recycling process can lead to a decline in material performance. Despite this, using recycled plastics is an important step toward a circular economy.

Bio-Based Plastics (e.g., PLA)
Bio-based plastics, derived from renewable resources like corn starch or sugarcane, are compostable and help reduce reliance on fossil fuels. PLA is a green, biodegradable alternative to traditional plastics. However, it is important to note that bio-based plastics require specific conditions for composting.

Foam Alternatives:

EPE and EVA Foam (Focusing on Recycled and Sugarcane-Based Options)
EPE foam is reusable and recyclable, while EVA foam is also recyclable. More sustainable sugarcane-based alternatives are emerging, offering more eco-friendly options. PU foam is an affordable choice that requires less energy to produce. These foam alternatives offer businesses more environmentally conscious choices.

Biodegradable Foam Fillers (e.g., Corn Starch-Based)
Traditional plastic foam peanuts are difficult to recycle and degrade, but biodegradable foam fillers made from plant-based materials like corn waste provide an eco-friendly solution. These fillers can dissolve in water or be composted, making it easier for consumers to dispose of them in an environmentally friendly manner.
