Description

Stacking film for refill bag

The present invention relates to laminated films and film containers. In more detail, this invention relates to the laminated | multilayer film which laminated | stacked the film of the vinyl resin containing a silicone oil, and 1-4 layers of general lamination films, and the film container made from this.

Film containers are used to conveniently package products at minimal cost to enable refilling into previously used containers without the need to purchase products, including containers each time, such as in detergents and hair cosmetic products. Conventional film containers are now very favored by consumers because of easy volume reduction and low price when discarding, but when refilling the refilled product into this product container, the contents are released slowly due to the friction between the inner surface of the film container and the contents. In addition, there was an inconvenience of having to throw away the contents remaining much.

In order to solve this inconvenience, domestic and foreign liquid product manufacturers sometimes sell the product in a film container with a cap so that the outlet can be inserted into the product container. This cannot be prevented, and the cost of the cap is excessively generated and the problem of foreign currency spillage is accompanied because the capping equipment has to be imported.

Therefore, there is a need to develop a packaging film and a film container that do not cause excessive costs while preventing the remaining amount of the content.

SUMMARY OF THE INVENTION An object of the present invention is to provide a laminated film and a film container made from the same, which can reduce the frictional force between the inner surface of the film container and the contents to facilitate the withdrawal of the contents in the container, thereby minimizing the remaining amount of the contents in the container. have.

The laminated film according to the present invention is characterized by laminating a film of a vinyl resin containing 0.3 to 3% by weight of silicone oil and a film for general lamination.

The film container according to the present invention is characterized in that it is molded into the laminated film.

Hereinafter, with reference to specific embodiments of the present invention will be described in detail.

The laminated | multilayer film which concerns on this invention is made by laminating | stacking the film of vinyl resin containing a silicone oil, and the film for general lamination.

The vinyl resin includes linear low density polyethylene or low density polyethylene. In this case, the linear low density polyethylene resin or the low density polyethylene resin alone or in a mixed state in which the silicone oil is mixed and other additives may be used to prepare a master batch, or linear low density polyethylene resin or low density polyethylene resin and other additives It is also possible to knead silicone oil to the existing masterbatch manufactured.

In the present invention, the silicone oil content of the laminated film is 0.3 to 3% by weight. When the silicone oil content is used at 0.3% by weight or less, the frictional force reducing effect of the film surface does not appear as expected, and the silicone oil is 3% by weight. In the case of the above-mentioned use, the lamination strength was lowered when the outer layer film was laminated on the inner layer film without a significant improvement in the frictional force reduction effect due to the increase in the silicone oil content.

Laminated film according to the invention is characterized in that the general laminated film is a nylon film. Nylon film has the advantage of being abrasion resistant, printing well and mass production at low cost.

A method that can be preferably used in the manufacture of the laminated film according to the present invention is to produce an inner film by the inflation method (dry lamination) or T-die extrusion lamination (T-die extrusion lamination) method The method of laminating | stacking an outer layer film is mentioned.

The film container according to the invention is characterized in that it is made of the laminated film.

Thus prepared film container can be used in kitchen detergents, hair cosmetics, fabric softeners and the like.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.

The following examples are intended to illustrate the invention and should not be understood as limiting the scope of the invention.

Example 1

A 150 μm thick film was prepared by melt kneading 0.1 wt% silicone oil in linear low density polyethylene.

Example 2

A 150 μm thick film was prepared by melt kneading 0.3 wt% silicone oil in linear low density polyethylene.

Example 3

A 150 μm thick film was prepared by melt kneading 1 wt% silicone oil in linear low density polyethylene.

Example 4

A 150 μm thick film was prepared by melt kneading 3 wt% silicone oil on linear low density polyethylene.

Example 5

A 150 μm thick film was prepared by melt kneading 4 wt% silicone oil on linear low density polyethylene.

Example 6

A 15 μm thick nylon film was laminated on the film of Example 2, and then a standing pouch type film container having a width of 140 mm and a height of 260 mm was prepared.

Example 7

After laminating a 15 μm thick nylon film on the film of Example 3, a film container of standing pouch type having a width of 140 mm and a height of 260 mm was prepared.

Comparative Example 1

A 150 μm thick film was made using only linear low density polyethylene.

Comparative Example 2

Using the film of Comparative Example 1 was prepared a film container in the same manner as in Example 6.

Experimental Example 1: Comparison of frictional force of the film

The frictional force of the film container according to the present invention was measured by the following method.

In order to compare the frictional force by composition, the friction values of the films of Examples 1, 2, 3, 4, 5 and Comparative Example 1 were measured using a friction tester, and the degree of smoothness of the films was evaluated by sensory evaluation.

At this time, the lower the friction value, the smoother the sensory evaluation, the lower the friction force of the film is interpreted.

division Friction force (unit: MU) Sensory evaluation Example 1 0.58 usually Example 2 0.28 lubricity Example 3 0.20 Very smooth Example 4 0.10 Very smooth Example 5 0.09 Very smooth Comparative Example 1 0.65 usually

As shown in Table 1, it was confirmed that the film of Examples 2, 3, 4, 5 in which the silicone oil was used in more than 0.3% by weight is significantly lower than the film of Comparative Example 1 using only polyethylene.

Experimental Example 2: Comparison of the content withdrawal from the film container

After filling 600 g of the cosmetic contents for hair with a viscosity of 50 PS into the film containers of Examples 6, 7 and Comparative Example 2 and sealing them, cut the upper left side of the film container so that the opening was 25 mm long, hang it upside down, and then flow for 15 seconds. Withdrawal amount was measured by measuring the amount of the contents. The higher the withdrawal amount was, the better the withdrawal property was.

In addition, the remaining amount of the contents was measured by the sensory evaluation, and the evaluation method is to divide the film container products of Examples 6, 7 and Comparative Example 2 filled with 600g of the contents to 10 women and refill the product container, and then the film The residual value remaining in the container was measured to obtain an average value, and the smaller the remaining content was, the more excellent the drawability of the content from the film container was evaluated.

division Withdrawal amount Content amount Example 6 200 g 29 g Example 7 220 g 26 g Comparative Example 2 140 g 42

As shown in the said Table 2, withdrawal property of the viscous content from the film container confirmed that the film container of Examples 6 and 7 was much better than the film container of the comparative example 2.

As a result of the synthesis of the above-described embodiments, the laminated film according to the present invention was found to have a significantly reduced friction compared with the conventional film. Significantly improved.

Accordingly, according to the present invention, a friction film between the inner surface of the film container and the contents is reduced by providing a laminated film formed by laminating a film of a vinyl resin containing silicone oil and a film for general lamination of 1 to 4 layers and a film container made therefrom. There is an effect to facilitate the withdrawal of the contents in the container, thereby minimizing the remaining amount in the container of the contents.
