Description
Technical Field
The invention relates to an aluminized film used in the field of packaging, in particular to an online-coated boiling-resistant enhanced aluminized film.
Background
The aluminizing film is a composite flexible package material formed by plating a layer of extremely thin metal aluminum on the surface of a plastic film by adopting a special process, wherein the most common processing method is a multi-level vacuum aluminizing method, namely, the metal aluminum is melted and evaporated at high temperature in a high vacuum state, so that the vapor of the aluminum is deposited and accumulated on the surface of the plastic film, and the surface of the plastic film has metal luster. Because the packaging material has the characteristics of a plastic film and metal, the packaging material is cheap, attractive, excellent in performance and strong in practicability.
After the plastic film is aluminized, the adhesive tape is used for checking the adhesion fastness of the aluminized layer of the aluminized film, the aluminized layer of the aluminized film cannot be peeled off, and the peeling strength of the aluminized film/the adhesive tape is more than or equal to 2.0N/15 mm; after the aluminizer is compounded with other films, the peeling strength of the aluminized surface of the composite film is sharply reduced after curing, complete aluminizing or most transfer phenomena can occur, and the peeling strength of the aluminized layer at the moment is generally 0.2-0.3N/15mm or even lower. If the aluminized film migrates, the vacuumized aluminized film package (such as a tea package) migrates aluminized over time, and large bubbles appear; in the case of the jelly cover, only the upper layer is peeled off when the jelly cover is peeled off. Such problems often occur particularly in the packaging of food products for cooking and poaching.
For example, CN 111423770 a discloses an acrylic resin material and a method for preparing the same, and the background art section refers to a simple process of aluminizing, i.e. in order to ensure the adhesion of the aluminized layer, a layer of primer may be coated on the base film, and then aluminizing may be performed. In addition, other materials can be compounded on the outer surface of the aluminum-plated layer through an adhesive, and the prior art discloses an acrylic resin material for bonding the compounded other materials. For another example, CN 111574952 a discloses a two-component solvent-free polyurethane adhesive special for aluminum-plated film lamination. Both of the above-mentioned prior arts disclose adhesives for lamination, both of which have excellent adhesive strength, so that the aluminum plating layer is easily detached and migrated once the adhesion between the aluminum plating layer and the base film is insufficient, especially at the time of later lamination or steaming. Accordingly, there is a need to provide a boiling resistant aluminum plating film that can enhance the adhesion of an aluminum plating layer.
Disclosure of Invention
The technical problem to be solved by the present application is to provide an on-line coating boiling-resistant reinforced aluminum-plated film to reduce or avoid the aforementioned problems.

Preferably, the mass ratio of each component of the on-line coating is respectively that the polyurethane adhesive: alumina particles: polyethyleneimine: polyethylene oxide: the ethylene-vinyl acetate copolymer is 100: (1-2): (3-5): (10-15): (5-10).
Preferably, the thickness of the polyester base film is 10-40 μm, the thickness of the on-line coating is 2-5 μm, and the thickness of the aluminum coating is 0.3-0.5 μm.
The application provides an online coating between the polyester base film and the aluminum-plated layer, and the aluminum-plated layer is fully dried and then subjected to vacuum aluminum plating, so that the thickness of the aluminum layer and the binding force between the film and the aluminum-plated layer can be improved. Because the aluminum plating layer has high fastness, the aluminum removing phenomenon can not occur, and the aluminum plating layer thickness is increased without aluminum removing.

In the illustrated embodiment, an in-line coating layer 2 is formed on one side of a polyester-based film 1 by in-line coating.
The on-line coating is a process of directly coating chemicals on the film by an on-line coating machine on a production line of the film so as to enhance and improve the surface function and the special physical and chemical indexes of the film and meet the use requirements of special products. Corresponding to the in-line coating is an off-line coating in which the film is produced and then coated. The online coating is different from the offline coating, and has the biggest characteristics of no need of rewinding, thin and uniform coating, high speed, high efficiency and low cost. Compared with the off-line coating technology, the on-line coating has the quality basically the same as that of off-line coating, but the cost is greatly reduced.
In the application, the primer solution forming the on-line coating 2 is coated on a base film slab before or during the stretching of the polyester base film 1, and then the base film slab is stretched into a film with a required thickness, and the primer solution coated on the surface of the base film slab is solidified to form the on-line coating 2 at a high temperature during the stretching process along with the stretching thinning. In the process, the coating thickness of the bottom coating liquid is greatly reduced after the two-way stretching, so that the high-quality on-line coating 2 is obtained, and the film forming property, the ductility, the wettability and the bonding firmness of the bottom coating liquid forming the on-line coating are high.
In one embodiment, the in-line coating layer 2 is formed by curing a polyurethane adhesive, alumina particles having a particle size of 2 to 3 μm, polyethyleneimine, polyethylene oxide, and ethylene-vinyl acetate copolymer by in-line coating.

The aluminum coating layer has high adhesive force and peeling strength up to 4N/15mm after the surface online coating treatment. Because the aluminum plating layer has high fastness, the aluminum removal phenomenon can not occur, the shelf life of the contents is prolonged, and the fragrance retention is good. The adhesion force of the film and the aluminum plating layer is high, and the aluminum plating layer is increased in thickness without aluminum removal, so that the aluminum plating layer can have higher barrier property by increasing the thickness of the aluminum plating layer; the film has stronger water resistance and temperature resistance. The on-line coated boiling-resistant enhanced aluminum-plated film is suitable for high-grade packaging of various solids and liquids such as milk powder, coffee, cosmetics, jelly, wine, beverage, pesticide, snack packaging and the like, can prolong the quality guarantee period of contents, and has good aroma retention; can replace the package of partial aluminum foil composite structure; the packaging bag can be used in occasions with high water resistance, and the liquid packaging is improved; can be used for pasteurization.
