Grade:MF803A
Product: Hot Melt Adhesive Granules for multi-layer co-extruded high-barrier packaging film.
Decriptions
1. the hot melt adhesive is a solid at room temperature and will melt into a liquid only when it reaches the melting point. It is a solid at room temperature and easy to transport and store.
2. it has strong viscosity and can act on many objects.
3. it is easy to use and the bonding time is short, which can save more time for users.
4. environmental protection and no pollution.

There are many factors that affect the use effect of hot melt adhesive. Firstly, one of the reasons is that the viscosity of the hot melt adhesive itself is not strong. Secondly, it is also related to the object of use of the hot melt adhesive. The same hot melt adhesive will show different viscosities on different items. It is recommended to select the special hot melt adhesive for the corresponding material; The temperature of the melt adhesive is also an important factor. Too high or too low will affect the use effect of the hot melt adhesive. It is recommended to use a special machine to keep the temperature within the use requirements.
MF803A is a maleic anhydride functionalized polyethylene mixture, easy to form film,with excellent processablility and adhesive strength, realizes the bonding of polyethylene resins and PA(Nylon) resins.
It is a modified polyolefin with functional groups to bond firmly to common Polyolefin, Polyamide(Nylon), Ethylene-vinyl -alcohol (EVOH).Since polyolefin itself have no functional groups, it does not adhere to other materials. So we incorporate functional groups into the Polyolefin-Resin to endow the outstanding adhesiveness to other materials without losing all the characteristic benefits of the polyolefin.
Advantages
- Strong Adhesion:Adhere to PA(Nylon) etc. strongly by thermal reaction. And it bonds strongly to PE resins and PA(Nylon) resins and keeps its polyolefin characteristics also.
- Durability:It can maintain excellent adhesiveness under the the harsh conditions in the thermal aging , hot water, cold water, low temperature,included chemical resistance.etc.
- Simple and easy processing: It can be processed in conventional extrusion equipment which is designed for plyolefin processing,doesn’t require special production equipment and the process condition is similar to common polyolefin.
Chemical Structure
Composition: Maleic Anhydride fuctionalized polyethylene mixture.
Application
MF803A adhesive resin is widely used as a binder for Food and Chemical packaging films, air-bubble films, balloon films, such as films for beef jerky, cake, candy, cereals, chicken, sea food, pet food, frozen food, mayonnaise, meat, edible oil, wheat, dried fruit, instant food, tomato ketchup, paste, pastry, rice, sugar, cream , etc.
