Inverted box motion flow wrappers represent a highly specialised, premium packaging solution. They are engineered to solve the most difficult packaging challenges by combining two distinct technologies: an inverted bottom-film-feed system and a long-dwell “box motion” sealing head.
The inverted design allows delicate, sticky, or difficult-to-handle products to be gently carried on the film, eliminating friction and potential damage. Simultaneously, the box motion sealing head provides the extended dwell time required to create high-integrity, fully hermetic seals, even with thick or complex films.
This makes it the definitive choice for high-value fresh food products—such as raw meat, poultry, fish, and soft cheeses—that require both extremely gentle handling and Modified Atmosphere Packaging (MAP) for extended shelf life.
This is the ultimate solution for products that are both difficult to handle and require a perfect, gas-tight seal. It addresses challenges that neither a standard box motion nor a standard inverted wrapper can solve alone.
Record Packaging Systems preventative maintenance contracts offer a comprehensive solution covering all types of packaging machinery and accessories. This ensures the operational integrity of your equipment.
Our extensive stock covers various machine models and generations, allowing us to cater to a diverse range of customer needs. By supplying high-quality, genuine parts, we guarantee the optimal performance and longevity of our packaging equipment.
The film reel is mounted below the infeed, creating a "carpet" that gently supports and carries the product through the machine, eliminating the need for pushing.
The long-dwell sealing jaws move with the product, applying heat and pressure for an extended period. This is the key to creating robust, gas-tight hermetic seals for MAP.
The system is designed from the ground up for Modified Atmosphere Packaging, with integrated gas lances and controls to flush the pack with a precise gas mixture before final sealing.
Typically built with stainless steel, cantilevered frames, and sloped surfaces to meet the stringent sanitation standards of the fresh food industry, allowing for fast and thorough cleaning.
Multiple independent servo motors provide precise, synchronised control over the infeed, film, and sealing head, ensuring smooth handling of delicate products and enabling fast, repeatable changeovers.

It combines the gentle product handling of an inverted feed with the high-integrity hermetic sealing of a box motion head.
When you have a product that is both difficult to handle (sticky/soft) and requires a perfect gas-flushed seal for shelf life.
Many models are built with stainless steel frames specifically for the stringent hygiene of the meat and dairy sectors.
Yes, the bottom-feed film support is highly effective for heavier items that are difficult to push.
It excels at sealing thicker barrier films and complex laminates that require extended heat penetration.
