Paper & cardboard packaging successfully replace plastic packaging

Paper and cardboard packaging can successfully replace plastic packaging by leveraging their sustainability, recyclability, and innovative design. Here's how:

• Eco-Friendly Materials: Companies like PUMA have transitioned to 99.5% paper packaging, using recycled or FSC-certified sources. This significantly reduces plastic waste.
• Innovative Barrier Solutions: Researchers at Northwestern University have developed graphene oxide coatings that make paper packaging resistant to water and oil, enhancing durability.
• Industry Adoption: Retailers like Co-op are replacing plastic with cardboard punnets and fibre-based packaging, cutting over 100 tonnes of plastic annually.
• Recycling & Composting: Unlike plastic, paper-based packaging can be easily recycled or composted, reducing environmental impact.
• Consumer Preference: Studies show that 73% or consumers prefer sustainable packaging, pushing businesses to adopt paper-based alternatives.

While paper packaging is making strides, challenges remain, such as cost, durability, and moisture resistance. However, ongoing innovations-like improved barrier coatings and industry-wide commitments-are making paper and cardboard viable replacements for plastic.

Glue a window-patch in cardboard packaging

Gluing a window patch in cardboard packaging involves attaching a transparent film over a cut-out section to showcase the product inside. Here's how it's done:

1. Prepare the Film: Cut a clear plastic sheet (like PET or PVC) to fit the window opening.
2. Apply Adhesive: Use a strong, transparent glue or specialised adhesive designed for packaging films.
3. Position the Patch: Carefully align the film over the cut-out section.
4. Press & Secure: Apply even pressure to ensure a firm bond.
5. Drying time: Allow the adhesive to complete set before handling.

Use bioplastics in combination with paper & cardboard

Several bioplastics can be combined with paper and cardboard to enhance durability, moisture resistance, and sustainability. Here are some key options:

• PLA (Polylactic Acid): A biodegradable plastic derived from corn starch or sugarcane, often used for coatings and laminations.
• Bio-PE (Biobased Polyethylene): Made from renewable sources like sugarcane, it provides flexibility and water resistance.
• PHA (polyhydroxyalkanoates): A compostable bioplastic that can be used for coatings and films.
• Cellophane: A biodegradable film made from cellulose, ideal for transparent packaging.
• Starch Blends: Derived from plant starch, these materials can be used for coatings and laminations.
