GT6e

Automatic, extra-large capacity, high-speed, in-line tray sealing system with full vacuum facility designed to cut labour costs.

Capable of 96 Vacuum/Gas packs per minute on a 8 impression tool; the GT6e is a high throughput modular, single-lane, linear, heat-sealing system. It is designed to run in conjunction with auxiliary equipment such as tray de-nesters, fillers, multi-head weighers and labellers, combining into a stand-alone, fully automatic production line.

At the core of the 'e' design is its flexibility to perform any style of heat seal to a pre-formed tray, be that atmospheric, MAP, VMAP, Skin, Skin Plus, or Skin Deep. Each of these options can be added now or at a later date, or indeed removed as necessary. This flexibility provides the user with the assurance that whatever the latest packaging trend might be, they have equipment suitably geared for the future.

MAP

Modified Atmosphere Packaging

Modified Atmosphere Packaging is a food packaging method where the Earth's normal breathable atmosphere has been modified by either a single gas or a mixture of gases. It is generally used with a barrier film with low oxygen transmission and is sometimes referred to as Gas Flushing.

The atmosphere in an MA package may contain N2, O2, CO2. Each food product has its own ideal gas mixture to ensure the longest shelf life possible.

The Gases

Carbon dioxide (CO2)

Carbon dioxide inhibits the growth of most aerobic bacteria and moulds. Generally speaking, the higher the level of CO2, the longer the achievable shelf-life. In most cases where CO2 is needed to control bacterial and mould growth, a minimum of 20-30% is required. However, CO2 can be absorbed by fats and water and in some cases cause pack collapse.

Nitrogen (N2)

Nitrogen is an inert gas and is used to exclude air; it is also used as a balance gas (filler gas) to make up the difference in a gas mixture. It helps prevent pack collapse where the CO2 has been absorbed. For modified atmosphere packaging of dried snack products, 100% nitrogen is used to prevent oxidative randicity.

Oxygen (O2)

In many foods oxygen should be excluded but there are often good reasons for it to be present in the map gas mixture.

To maintain fresh, natural colour in red meat
To maintain respiration (in fruit and vegetables)
To inhibit growth of anaerobic organisms (in some types of fruit and vegetables)

Ideal residual oxygen levels are dependent upon each customer's shelf life trials and tolerances.

Food manufacturers should seek the advice of Food grade gas suppliers before deciding which gas supply mode is the most appropriate for their needs.

Guidelines have been quoted in the CCFRA (Campden and Chorleywood Food Research Association) map guide document.
