Description

A kind of ultra-low temperature heat-sealing antibacterial wrapping paper

technical field

The utility model relates to the technical field of wrapping paper, in particular to an ultra-low temperature heat-sealed antibacterial wrapping paper.

Background technique

Candy wrappers in the prior art include cold-sealed twisted wrappers and heat-sealed wrappers, the former as described in CN204080544U, the wrapper structure includes a paper base layer, an ink layer and an isolation varnish layer covering the ink layer. A coating area is positioned on the varnish layer, the coating area is located close to the left and right sides of the wrapping paper, and the coating area is positioned to coat cold sealant. Another example is the ultra-light candy wrapper described in CN203583288U, comprising a fully transparent first cellophane layer, and being arranged on the first natural edible fiber glue layer below the first cellophane layer, and being arranged on the first natural edible fiber glue layer The parchment layer below, and the second natural edible fiber glue layer arranged under the parchment layer, and the second cellophane layer arranged under the second natural edible fiber glue layer.

Due to the difference in the contents, when using the above-mentioned two kinds of packaging, the content with a large oil content will have the phenomenon of oil leakage. In addition, the oil leakage is also easy to breed bacteria, which is not conducive to the preservation of the content. The higher sealing temperature during packaging production will cause deformation and qualitative changes to the contents, which will affect the characteristics of the final product.

The material layer is a plastic film layer and/or an aluminum foil layer, a primer layer is provided between the ink layer and the inner substrate layer, the primer layer contains at least one photocatalytic primer layer, and the sealing layer is an ultra-low temperature hot melt adhesive layer or heat seal layer. The two optional ranges of the sealing layer both have ultra-low temperature heat sealing characteristics, meeting the packaging speed requirement of 300-500 packs/min.

By adding a plastic film layer and/or an aluminum foil layer, the barrier performance of the film body can be improved, especially the addition of an aluminum foil layer can enhance the temperature resistance and stiffness of the wrapping paper. The primer layer is composed of at least two primer layers, and the introduction of the photocatalytic primer layer can improve the ability of the wrapping paper to block bacteria.

In order to ensure the barrier performance of the wrapping paper, reduce the amount of filter material used, and reduce production costs, the preferred technical solution is that the plastic film layer is an aluminized film, and the aluminized layer of the aluminized film is connected to the primer layer. In addition, the stiffness of the aluminized film is high, which can ensure the crisp appearance of the candy paper packaging.

The preferred technical solution is that the surface resistance value of the aluminized film is 1.0-2.5Q.

The preferred technical solution is that the undercoat layer comprises a first undercoat layer and a second undercoat layer laminated, the first undercoat layer is a photocatalytic undercoat layer, and the photocatalytic undercoat layer is Nano-titanium dioxide modified polyvinylidene chloride film layer or nano-titanium dioxide-modified polyvinyl alcohol coating, the second primer layer is polyurethane coating, and the first primer layer is attached to the substrate layer.

In order to ensure that the wrapping paper has good barrier properties to ultraviolet rays, water vapor, oxygen and grease, the preferred technical solution is that the oil-proof paper layer and the base material layer are connected by an adhesive layer.

The preferred technical solution is that the plastic film layer is a coating layer. The thickness of the plastic layer obtained by coating can be controlled within a relatively low range, and the coating can produce various texture effects, with high transparency and burst resistance.

Advantage and beneficial effect of the present utility model are:

The ultra-low temperature heat-sealable antibacterial wrapping paper has a simple structure. By adding a plastic film layer and/or an aluminum foil layer to the wrapping paper, the barrier performance of the wrapping paper to animal and vegetable oils can be improved. By adding a primer layer containing a photocatalytic primer layer , can endow the wrapping paper with antibacterial properties, which is beneficial to the preservation of the contents of the wrapping paper. By adding an ultra-low temperature hot-melt or heat-sealing adhesive layer, it can effectively reduce the deformation or qualitative change of the wrapping paper contents due to heat sealing, and improve the packaging production. efficiency.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

The sealing layer 4 is an ultra-low temperature hot melt adhesive layer.

The greaseproof paper layer 1 and the substrate layer 2 are connected by an adhesive layer 6 .

Example 2

As shown in Figure 2, the difference between embodiment 2 and embodiment 1 is that the base material layer 2 is a plastic film layer 21; The sealing layer is a heat-sealing adhesive layer.

The surface resistance value of the aluminized film can be 1.0-2.5Q.

The primer layer 5 is composed of a first primer layer and a second primer layer, the first primer layer is a photocatalytic primer layer, and the photocatalytic primer layer is nano-titanium dioxide modified polybias The vinyl chloride film layer 51, the second primer layer is a polyurethane coating layer 52, the polyurethane coating layer 52 is attached to the ink layer 3, and the first primer layer is attached to the substrate layer 2.

Example 3

In embodiment 3, the photocatalytic primer layer is composed of nano-titanium dioxide modified polyvinyl alcohol coating 53, that is, nano-titanium dioxide-modified polyvinyl alcohol coating 53 replaces the nano-titanium dioxide-modified polyvinyl alcohol coating 53 in the primer layer in embodiment 2. Vinylidene chloride film layer 51.

Nano-titanium dioxide modified polyvinylidene chloride film layers were used in Examples 1 and 2.
