Ambition level considerations: An ambitious plastic minimization target for highly applicable packaging types, such as multi-wrapping (if elimination is not an option), is 80% by 2030. Achieving this target will often require product and/or packaging redesign, such as switching from six-pack wraps to multi-pack handles (e.g., Nature Multi Pack by KHS). Shifting to a concentrated product (e.g., concentrated all-purpose cleaners) could make even higher minimization ambition levels possible. After a careful assessment of recyclability, ambitious smartweighting can minimize around 30% of plastics. For example, ALPLA recorded a 28% material reduction by lightweighting milk bottles while WRAP reports a 30% material reduction in stretch film following the simple modification of existing equipment (7). In other cases, only a 10-15% material reduction is feasible, such as reducing the size of liner back seals by using a new sealing approach (e.g., Marks & Spencer salad packaging (7)).
Considerations on different packaging formats: Minimization is currently most applicable for the following types of packaging:
Bottled products such as beverages, cleaning products, and personal care products; PET/HDPE/LDPE/PP bottles for syrup or other condiments; and trays and pots used for products like yogurt, fruit, and vegetables – high potential.
Stretch wrap used for fruit and vegetable and other wrapping, pouches, and plastic bags, such as for bread – moderate to high potential.
