Embodiment 1-3

[0063] EXAMPLES The absorbent layer of the coextruded film is Polymer A (melting point 200°C) and Polymer B (melting point 200°C) shown in Table A, both of which are copolyetheresters.

[0064] Table A

[0065] Example

Comonomer content of the polymer

Polymer A

45% by weight 1,4-butylene terephthalate, 55% by weight ethylene oxide / epoxy

Propane copolyether terephthalate. The calculated ethylene oxide content was 33%.

Polymer B

42% by weight of 1,4-butylene terephthalate, 12% by weight of 1,4-isophthalamide

Butylene glycol ester, 36% by weight ethylene oxide / propylene oxide copolyether terephthalic acid

Ester, 10% by weight ethylene oxide / propylene oxide copolyether isophthalate. calculated

The resulting ethylene oxide content was 13%.

Embodiment 4 and 5

[0076] A five-layer coextruded blown film was prepared with the following layer structure:

[0077] LLDPE (Dowlex 2045G) / 4104 / Nylon 6 (Ultramid B35F) / 21E787 / Polymer A, the thickness of each layer is 15 / 10 / 20 / 10 / 25 μm, respectively. A 510mm wide sample of this film was thermally laminated to a 535mm RL oriented polyester film (film of Example 4).

[0078] A five-layer coextruded blown film was prepared with the following layer structure:

[0079] LLDPE (Dowlex 2045G) / 4104 / Nylon 6 (Ultramid B35F) / 21E787 / Polymer A, the thickness of each layer is 22 / 10 / 20 / 10 / 18 μm, respectively. A 510 mm wide sample of this film was adhesive laminated to a 535 mm 50 micron polyethylene / polyamide / polyethylene shrink film (film of Example 5).

[0080] The membranes of Examples 4 and 5 were then coated with the smoke liquor using a method similar to that described above in Examples 1-3 at the tunnel drying temperatures shown in Table 2. The smoke preparation coated film was sealed ...

Embodiment 6

[0084] A five-layer blown film with the following layer structure:

[0085] polypropylene / 50E725 / Nylon 6 / 21E787 / Polymer A, the thickness of each layer is 8 / 3 / 8 / 6 / 18μm, and the width is 1050mm, passing between the 1020mm rubber support roller and the 44 square gravure roller with a doctor blade. The gravure roll is located in a container containing 15% ethanol and 85% smoke liquor (pH value is about 3.0, total acidity is 7 to 10% acetic acid by weight, smoke flavor compound is 30 to 40mg / mL, aldehyde and ketone compound content is 40 to 50% by weight with a density of about 10 lbs / gal) in the tank. The line speed of smoke liquid coating is 120ft / min. After coating, the film is dried by passing through a hot air tunnel. The hot air temperature of the tunnel dryer in four zones was set at 250°F (121°C), 350°F (177°C), 350°F (127°C), 400°F (204°C). The smoke coating weight of the film was 18 g / m2. The coated film was then cut from top to bottom to a width of 1020mm and a...

Abstract

A process for producing a film having incorporated or applied thereon or therein an additive such as liquid smoke is provided wherein the film comprises a liquid absorbent layer and an impermeable layer. The films can be used for producing a tubular casing or shrinkbag.

Description

field of invention [0001] The present invention relates to a process for the preparation of laminated films for packaging food products and / or as casings for food products. Background of the invention [0002] Food casings are made from natural materials such as cellulose or animal intestines or synthetic materials such as fibres. Food is packed into casings. When a smoked product is desired, the casing food can also be subjected to treatments such as smoking, where the product is hung indoors and exposed to the hot smoke from burning wood. In methods employing a liquid smoke, the liquid smoke may be applied to the surface of the food by showering, misting or spraying. [0003] There are some disadvantages involving the use of cellulose and fibrous casings in the smoking method. Smokers are difficult, expensive to clean and expensive to clean after hours of cooking at high temperatures, the soot and meat products left on almost every surface inside the oven from roasting ...
