Abstract

The utility model discloses a macroporous film structure with favorable tactility. Small holes of small holing are arranged at the position where the second face of the film extends to the first face; big holes are arranged at the position where the first face of the film extends to the second face, and the big holes form protruded film angles; the second face of the film is treated as the front face contacting with skin while in application. As the big holes of the film are perforated by vacuum or mechanical means and the film of each perforation core is forcibly torn, the torn film prominences form on the film face after the perforation is made, and the film prominences cause the surface of the film to be rough velour. Using the velour as the front face of the absorption article may increase the contact elasticity between the absorption article and the skin and improve using comfort. Meanwhile, increase the roughness of the absorption article and resist the flowing velocity of body liquid and further prevent the body liquid from leaking from sides.

Description

Macropore sense of touch membrane structure

Technical field

This utility model is about a kind of thin film, is meant a kind of macropore sense of touch membrane structure that is widely used in disposable sanitary articles such as medical care mattress, women use sanitary napkin, protective pad, diaper as lining especially.

Background technology

Medical care with disposable sanitary articles such as mattress, sanltary towel for women use, protective pad and diaper in, particularly be purpose such as reach dry and comfortable, breathe freely, prevent to bleed back in women's disposable sanitary articles and the diaper, the widely-used making hole film of people is as lining.Known making hole film is that the employing TPO is a raw material, extrudes curtain coating through screw extruder and forms plastic sheeting, and make making hole film through the vacuum punching, and this making hole film has the open-celled structure in one deck hole at least.Cooperate shown in Fig. 1,2, its production method is a macropore 2 ' and aperture 3 ' all is that from thin film 1 ' first 11 ' punches in the same way to second 12 ', simultaneously with first 11 ' of this thin film 1 ' as the front that is applied to film product, and adopt its first 11 ' surface smoothing of making hole film of this explained hereafter, has plastic sheeting inherent plastic sense of institute and gloss, contact closely with human body skin easily, then in use cause the discomfort of user easily.

The utility model content

The purpose of this utility model provides a kind of macropore sense of touch membrane structure with matte sense of touch, so that it has softness, skin-friendly and use comfortable effect when being applied to required article surface.

For achieving the above object, solution of the present utility model is: a kind of macropore sense of touch membrane structure, and it is to be extended with the less aperture of perforated area to first face on second of thin film; First oriented second face at thin film is extended with macropore simultaneously, and this macropore forms the thin film angle of projection on second of thin film; Second use front that conduct contacts with human body skin when thin film is used of thin film.

The aperture area of described aperture is not more than the perforated area of macropore.

Described macropore is the funnel type perforate.

The perforated area of described macropore is 0.01mm ²To 6mm ²

The best perforated area of described macropore is 0.1mm ²To 2.5mm ²

After adopting such scheme, because this utility model is in when punching with thin film, change inherent manufacture of beating macropore and aperture in the same way, it is the mode that adopts the secondary punching, because this thin film is when big or small hole forming, be to adopt vacuum or mechanical type molding, the thin film of its each Kong Xin is ripped by force, thereby has the thin film angle projection of being ripped on second of the thin film that can be after macropore forms, these thin film angle projectioies can make second formation rough " matte " of thin film just, utilize this " matte " to contact with human body skin, can possess following advantage as the front that is applied to hygienic article:

1, increases the contact resilient of film product and skin, improve the comfortableness of using;

2, increase the roughness of film product, can stop the flow velocity of body fluid, further prevent the body fluid side leakage.

The specific embodiment

Cooperate Fig. 3 to shown in Figure 6, perforated film structure of the present utility model is to be extended with funnel type macropore 2 at first 11 of plastic sheeting 1 to second 12, and the perforated area of macropore 2 can be 0.01mm ²To 6mm ², its best perforated area is 0.1mm ²To 2.5mm ²This macropore 2 can form the thin film angle 21 of projection on second 12 of plastic sheeting 1; Simultaneously form the less aperture 3 of perforated area to first 11 on second 12 of thin film, these aperture 3 aperture areas are not more than the perforated area of macropore 2, second the 12 use front that conduct contacts with human body skin when thin film is used of thin film.

Because this perforated film 1 is the front that second 12 conduct of its macropore 2 molding of employing is applied to hygienic article, because of this thin film 1 when macropore 2 molding, be to adopt vacuum or mechanical type molding, the thin film of its each Kong Xin is ripped by force, thereby can have thin film angle 21 projectioies of being ripped at second 12 of thin film after macropore 2 forms, these thin film angle 21 projectioies can make the reverse side 12 of thin film 1 form rough " matte " just.Cooperate shown in Fig. 7,8, utilize this " matte " as the front that is applied to hygienic article, above the thin film angle 21 of projection can increase the contact resilient of film product and skin, improve the comfortableness of use; Also can increase the roughness of film product simultaneously, can stop the flow velocity of body fluid, further prevent the body fluid side leakage.
