Tie Layer for Multi-layer Co-extrudbale Artificial Sausage Casings

Tie Layer for Multi-layer Co-extrudbale Artificial Sausage Casings



*** Tie Layer for Multi-layer COEX Artificial Sausage Casing Film
*** Tie Layer Adhesive Resins for Multi-layer Co-extruded Nylon Barrier Sausage Casings




Industrial Background

Sausage casings are raw materials which contain filling of sausages. Casings are important packaging materials for sausage and play an significant role in maintaing the quality of meat product and extending their shelf life.They may be edible or inedible. In terms of raw materials used, sausage casings may be broadly classified into natural casings and artificial casings.As the demand for casings increases, the market for supply of naturral casings is in short, thus providing opportunities for the emergence and development of artificial sausage casings including plastic casings, cellulose casings and collagen casings. Among them, the market demand for nylon composite casing film with high oxygen and steam resistance, high temperature resistance, and retortability is increasing year by year. This nylon composite casing membrane,Using high-quality nylon as raw material, the casing is high temperature resistant and can be steamed. The casing has high strength and stable diameter during enema, and is suitable for various punching machines.

This kind of Nylon casing film can effectively maintain the color and moisture of sausages, and can be made into various styles with sharp edges and corners according to customer molds. Some products are UV-resistant, have the advantages of not fading, and extending shelf life. They can be used for the outer packaging of steamed hams and can also be frozen. Used to press molds to make special-shaped sausages, such as sandwiches, Western-style ham, bricks, etc. After filling, the surface is smooth and flat, has a long shelf life, the shrinkage rate can be customized according to customer requirements, and is tear-resistant. In response to this customized demand, Liaofan complied with market demand and combined its many years of bonding technology and barrier experience to successfully develop a series of multi-layer co-extruded nylon composite casing film adhesive resins. Due to its strong bonding strength and excellent processing performance, it has quickly gained a remarkable market share and accumulated a good reputation in the industry.



Product Descriptions

Liaofan PG series co-extrudable tie layer adhesive resins for multi-layer co-extruded nylon composite casing film are anhydride-grafted low-density polyethylene (LLDPE). Maleic anh ydride groups are chemically grafted on the non-polar polyethylene molecular chain. They are copolymer resins made of high-strength properties and has successfully achieved good bonding between polyethylene (PE) resin and PA resin. They can be used in composite barrier films, casing films and other fields. This series of products not only perfectly inherits the excellent characteristics of PE and LLDPE's temperature resistance and high transparency, but also extends the advantages of excellent processing performance, good chemical corrosion resistance and enhanced puncture resistance of finished products. They are preferred food-grade tie layer adhesive resins for multi-layer COEX nylon barrier sysentic/artificial sausage casing films.


Product Advantages

*** Super strong adhesion between PE and PA.

*** An ideal food-grade tie layer adhesive resin.
*** Support to enhance the anti-chemical property of casings.
*** Support to enhance the puncture resistance property of casings.
*** Little crystal point, no gel content.


Industrial Tests for Casings(reference)

*** Puncture Resistance

*** Tear Test

*** Film Impact Test



*** Friction Coefficient Test

*** Tensile Strength at break


*** UV Test


*** WVTR/OTR Test
