Extending Cake and Pastry Shelf Life with Modified Atmosphere Packaging (MAP)

Hello, I am Robert Murphy, Sales Director at Record Packaging Systems Ltd. In my role, I spend the majority of my time on the road, walking the factory floors of UK bakeries and speaking with production directors about retail compliance. I frequently consult with businesses looking to scale up from regional distribution to major national supermarket contracts, where shelf-life requirements become a critical hurdle. To overcome this, we regularly configure our flow wrappers for Modified Atmosphere Packaging.

How MAP Works on a Flow Wrapper

When delicate, high-fat bakery items are exposed to oxygen, they quickly spoil due to mould growth and staling. A flow wrapper configured for MAP solves this by injecting a precise mixture of food-grade gases, usually carbon dioxide and nitrogen, into the film tube just before the final seal is made. This gas mixture displaces the oxygen inside the bag, creating an environment that preserves freshness.

For MAP to be successful, you must achieve a hermetic, gas-tight seal. Even a microscopic leak will let oxygen back in, spoiling the product. This is why we recommend using our box motion flow wrappers, such as the Record Panda or Jaguar models, for MAP applications. The extended dwell time of the reciprocating sealing head ensures that the film is completely fused, guaranteeing a reliable gas barrier.

“From a sales and commercial perspective, extending product shelf life by even a few days completely transforms a bakery’s distribution potential and drastically reduces waste.” – Robert Murphy

Real-World Benefits for UK Bakeries

By utilising MAP on your packaging line, you can:

• Significantly reduce product returns and waste due to premature spoilage.
