Molded Pulp Punnets for Mushrooms and Berries: Ventilated, Plastic-Free Produce Packaging

Mushrooms and berries are fragile, moisture-sensitive produce that bruise and sweat in sealed plastic punnets. Molded pulp forms ventilated punnets with open-cell walls that let produce breathe, absorb excess moisture, and cushion against bruising — replacing plastic punnets with a recyclable, home-compostable tray that keeps delicate produce fresher and aligns with plastic-free produce sections.

The Scenario: Delicate produce, sealed plastic

Produce packaging faces three challenges:

Pain Points

• Mushrooms and berries bruise when pieces press together, and sweat in sealed plastic traps that accelerate spoilage;
• Plastic punnets are non-recyclable and increasingly banned in produce sections;
• Retailers want packaging that keeps produce fresh while meeting plastic-free targets.

The Solution: Three molded pulp punnet solutions

Molded pulp offers three solutions for mushrooms and berries:

1. Ventilated open-cell walls Open-cell walls let produce breathe, reducing condensation and slowing spoilage.

2. Moisture-absorbing pulp Pulp naturally absorbs excess moisture, keeping berries dry and firm.

3. Recyclable, home-compostable trays All-pulp punnets replace plastic and compost at home, meeting plastic-free targets.

The Result: Produce stays fresher, plastic-free

With these solutions, mushrooms and berries arrive firmer and fresher, cutting spoilage and shrink. The compostable punnet wins over plastic-free shoppers.
