CONSTITUTION:A resin (e.g. polyethylene terephthalate resin) mixed with 0.1-30wt.% of a triphenylphenyl compound of formula 1 (R<1> to R<3> are H, OH, amino, nitro, a halogen, an alkyl or an alkoxy; X is H, a halogen, OH, amino or ether residue) (e.g. triphenylmethane) by a Banbury type mixer at 160 deg.C at 60rpm for 5 minutes under purging with nitrogen and press-molded at 160 deg.C under 50kg/cm<2> to give a film. Then, this molded article is irradiated with a radiation such as electron rays to convert the triphenylmethyl compound into a free radical of formula II to give the objective molded article of resin having barrier to oxygen, having scavenging action on oxygen by reaction of the formed radical with oxygen.

2. Description of the Related Art There are various functions required for packaging,
Mechanical protection, safety, hygiene, workability, productability (transparency, printability, heat sealability), convenience, economy, etc. are mentioned, but various gas barrier properties as content protection are foods. It is an important property that influences the storability of lactic acid, and the need for it is increasing due to diversification of distribution patterns, packaging technology, regulation of additives, and changes in taste. And
It was also a weak point of general plastic materials. Deterioration factors of food are oxygen, light, heat, and water, and oxygen is the causative substance. The barrier material is an indispensable material for effectively blocking this and at the same time for controlling deterioration of food such as gas filling and vacuum packaging.
In addition to oxygen gas, various gases, organic solvent vapor,
Due to its barrier function such as aroma, it is very effectively used in the fields of carbon dioxide beverage containers, rust prevention, odor prevention, sublimation prevention, cosmetics, agricultural chemicals, and medical treatment.

Among the films made of thermoplastic resin, particularly oriented films of polypropylene, polyester, polyamide and the like have excellent mechanical properties, heat resistance and transparency and are widely used as packaging materials. There is. However, when these films are used for food packaging, their oxygen permeability is insufficient because their gas permeability is too large, causing alteration of the contents such as due to oxidative deterioration or due to aerobic microorganisms. In many cases, a method such as laminating another film layer having a good oxygen barrier property is usually adopted. The most typical means is to laminate a metal foil such as aluminum or to deposit these metals on the surface of the thermoplastic resin film, and the excellent gas barrier property, especially oxygen barrier property is effectively utilized. There is. However, these aluminum laminates and vapor-deposited films are opaque and their contents are not visible when food is packaged with them. Due to such drawbacks, a film having excellent transparency and excellent oxygen barrier property is increasingly desired.
