|  | Listed below are some of our films that have been used in typical packaging applications in different markets. Every application is different and the use of any packaging product should be rigorously tested before being used commercially. (See guidelines below.)
The market
The bakery market can be broken down by volume, with speciality bakers producing 50%, industrial bakers accounting for a further 35% and the remaining 15% composed of semi-industrial bakery products. Market growth, by value, has been limited over the past few years due to the maturity of many of the larger markets and the conservative attitude of many bakery product manufacturers towards using flexible packaging for crushable food products.
Bakery products range from heavyweight breads to delicate French patisseries. A wide range of packaging formats are employed and gas-flushed structures are also used.
Product characteristics

Main factors of degradation
Impact of humidity: over-drying can cause texture change with a loss of softness; an increase of humidity can encourage mould growth and the development of yeast.
According to the Aw level and the amount of fat, the product needs to be protected against oxidation, loss of odour, and off-odour/taste contamination.
Preservation processes
- Thermal means: infrared, microwave
- Gas flush (the choice of the gas mix depends on the product composition – mainly Aw & fat content)
- Alcohol injection: ethanol is commonly used (either by direct injection or by spray pulverisation before wrapping)

Technical data and guidelines presented on this web site are based on tests, experience and information that ExxonMobil Chemical Films believes to be reliable and helpful. The films are presented for consideration but are not intended as a recommendation for use in any particular application. It is impossible to anticipate every application for which the products may be proposed and widely varying user's processing conditions may have significant impact on performance properties. For those reasons it is important that users undertake independent testing in order to verify the suitability of any product for any particular application. Users are also encouraged to discuss potential applications with representatives of ExxonMobil Chemical Films who can consider the specific conditions that may be encountered.
