Packaging, meats

Strength they are of interest as a streteh film for meat packaging and for cling-wrap purposes. Some EVA is used in coextrusion processes for the manufacture of laminated film. 

At the opposite end of the polyethylene spectrum are the so-called ultra low density products with a high concentration of short chain branching that inhibits crystallization. These materials are soft, flexible, and transparent we encounter these materials in applications such as medical tubing, meat packaging films, and ice bags.

PB film is usually made by the blown film process, but also can be cast oil drill lolls. Film applications include food and meat packaging, compression wraps, and hot-fill containers. The material can be formulated to provide a wide range of seal strengths for peelable or easy-opening packaging. 

Copolymers of PE with vinylacetate, acrylic acid ester and methacrylic acid increase the heat sealability, adhesion to other materials and seal strength and they improve the polymer s cold resistance and transparency. EVA in the form of shrink films are well suited for meat packaging because of their relatively high gas permeabilities.

The previously mentioned preference of Mb for CO over O2 results in the formation of the highly stable carboxymyoglobin (COMb), which is virtually indistinguishable by eye from OMb. COMb can form from any one of DMb, OMb, or MMb (Suman et al., 2006) and is much longer-lived than OMb. CO is usually used at levels of less than 1% to give a fresh color to meats packaged in anoxic conditions, which would otherwise appear brown (Walsh and Kerry, 2002).

EVOH can be extruded in films, blow molded, or injection molded. It can also be processed by coextrusion or lamination, in combination with PE, PP, PET, nylons, and other resins. Applications in packaging include flexible structures and rigid containers, as shown in Table 4.12. Typical applications are ketchup and barbecue sauce bottles jelly, preserves, vegetable juice, and mayonnaise containers and meat packages. Nonfood applications include packaging of solvents and chemicals.

Orientation of polymers enhances many of their properties, particularly the mechanical, impact, barrier and optical properties. Biaxial orientation has the added advantage of allowing this enhancement in two directions, avoiding any weakness in the transverse direction. Biaxial orientation is particularly important in films, where it allows the production of thinner films having superior mechanical, optical and barrier properties and, if required, the ability to shrink when reheated. For example, shrink and barrier properties are particularly important in meat packaging, whereas good mechanical and optical properties and no shrinkage are desired in box overwrap applications of tape cassettes and CDs. 

Oxygen and moisture absorbers have been used in bakery, pasta, and meat packaging to prevent oxidation and water condensation. If oxygen absorbers are not exactly antimicrobial, reduction in oxygen inhibits the growth of aerobes and moulds, in the same way as moisture absorbers [5].
