“Layer by layer” technology was used to create transparent, thin and high barrier polyethylene films to use in food packaging. These films were made by inserting successive layers of polyacrylamide and montmorillonite (Cloisite Na+, non-organic modification) grown onto a low density polyethylene (LDPE) film substrate submitted to corona treatment. Excellent oxygen permeability results were reached with only 9 bilayers, with a reduction of 99.92%, compared to the pure polyethylene. This allowed the oxygen barrier film to change from poor to high (3.66 cm3/m2·day), with a total thickness of 48 microns, due to the structure formed over the film to create a tortuous path for oxygen molecules. Optical properties were analysed, showing a ≥92% transparency in all samples. Thermal stability of polyethylene was slightly improved and this was attributed to nanoclays presence forming an insulating layer. The result of this research is a thin structured film which is a good candidate for common barrier films replacement in food packaging thanks to its high oxygen barrier capacity, optical transparency, microwaveability and recyclability.

Studies were done to determine the effects of packaging films and vacuum levels on the microbiology of bacon cured with nitrite or a combination of nitrite and sorbate in the curing salt mixture. High and low oxygen barrier films were used along with high and low vacuum levels for packaging systems. Growth of mesophilic, psychrotrophic and lipolytic organisms was restricted most with the combination of high barrier-high vacuum treatment. Vacuum level was more important than type of film in retarding bacterial growth as storage time progressed up to 28 d at 5°C. Sorbate combined with nitrite was more inhibitory than nitrite with no sorbate in the cure.

Pork loins were fabricated immediately (fresh) or stored in parchment paper for 6 d or stored in vacuum packages for 8 d. Chops were packaged in either a high oxygen-permeable (PVC) film or a high oxygen-barrier film (vacuum) to be displayed 4 d or 2, 6 and 10 d, respectively. High oxygen-barrier (HOB) film was superior to PVC film in maintaining desirable visual properties of chops. Chops had less off-odor in HOB film when they were held no longer than 3 or 4 d in HOB packages compared to extended periods of display. Pork loin chops packaged in high oxygen-barrier film can be displayed up to 6 d if chops are from fresh pork loins. Although visual scores for vacuum-packaged chops were acceptable for 10 d for all storage treatments, chops from the parchment paper and vacuum-packaged storage treatments had off-odors which were limiting factors in achieving long shelf life.

Organic–inorganic hybrid films are fabricated via an alternate assembly of a chitosan (CTS) polymer and hierarchical layered double hydroxide (H-LDH), which exhibit tremendous oxygen barrier properties with high stability as well as long-term maintenance.
