Machine Efficiency and the Impacts of Sustainable Packaging

Many primary packaging lines are no longer dedicated to a single product as SKUs increase, impacting line efficiency. Sustainable material changes may also create challenges.

According to a new report by PMMI Business Intelligence, there are challenges CPGs face when moving to more sustainable packaging. “OEMs need to work closely with material suppliers to test new materials and be part of the process when changes are being considered to present and suggest solutions for machine modifications or alterations,” said one Sr. Director of Plant Engineering at a confectionery.

Here are some of the areas that have been impacted, according to CPGs interviewed for the report:

Thermoforming Operations

• Substrates have different melting points and do not flow the same, causing performance issues when forming trays.

• Polypropylene (PP) is now a popular mono-material but running it on existing thermoforming packaging machines is more challenging than with other plastic materials.

Capping/Sealing Station

• Sealing is a challenge when filling varied shapes and sizes; a stronger seal is needed.

• Machines that can efficiently handle and seal lightweight plastic trays are needed to minimize food waste and materials.
