Problems solved by technology

[0003] Most of the existing care product packaging bags are aluminum-plastic composite packaging films, such as the patent of CN204384012 U name for the composite packaging film used for hygienic product packaging bags, and the disclosed packaging film is composed of PE layer and VMPE layer. , although it has good barrier properties, softness and heat-sealing properties, but the tear resistance and durability are poor, and it does not have covering properties, so it cannot meet market demand
[0004] In addition, the existing care product packaging bags are not easy to open, and most of them cannot be resealed or have poor sealing effect after being opened, which leads to bacterial invasion, deliquescence and oxidation of the care products, thereby shortening the storage life of the care products

Embodiment 1

[0045] Such as figure 1 Shown is a personal care product outer bag film with a film thickness of 30 μm according to the present invention, which sequentially includes a matting layer, a covering layer, an upper adhesive layer, a high barrier layer, a lower adhesive layer, a water-blocking layer, heat seal layer;

[0046] Wherein, the raw material of the matting layer is a mixture of EVA and matting materials, and the thickness is 18% of the total film thickness. The addition of matting materials makes the surface layer have a matte effect and has good flexibility, so that the outer bag film is more marketable. ;

[0047] The raw material of the cover layer is a mixture of LDPE and white masterbatch, and the thickness is 17% of the total film thickness. Since personal care products are commodities with privacy, the design of the cover layer can well cover the products contained therein, thus effectively It prevents embarrassment when customers choose and carry;

[0048] The ...

Embodiment 2

[0063] Compared with Example 1, the only difference is that a personal care product outer bag film with a film thickness of 40 μm was prepared. same.

Embodiment 3

[0065] Compared with the difference of Example 1, the only difference is: the raw material of the heat-sealing layer is Surlyn and EVA mixed in a mass ratio of 7:3, and all the others are the same as in Example 1, such as figure 2 shown.

Abstract

The invention relates to an outer bag film used for personal-care supplies. The outer bag film has a total thickness of 25-40 [mu]m and sequentially comprises a delustered layer, a covering layer, anupper bonding layer, a high barrier layer, a lower bonding layer, a waterproof layer and a heat-sealing layer, wherein the delustered layer is made of a mixture of 90 wt% of EVA and 10 wt% of delusteirng materials, the covering layer is made of a mixture of 80 wt% of LDPE and 20 wt% of white master batch, the upper bonding layer and the lower bonding layer are made of a mixture of 30 wt% of TIE and 70 wt% of LLDPE, the high barrier layer is made of EVOH, the waterproof layer is made of a mixture of 50 wt% of LDPE and 50 wt% of LLDPE, and the heat-sealing layer is made of a mixture of 70 wt% ofMLLDPE and 30 wt% of EVA. The invention further provides a preparation method of the outer bag film and a packaging bag made of the outer bag film.

Description

technical field [0001] The invention relates to the technical field of care product packaging, in particular to a personal care product outer bag film and a packaging bag thereof. Background technique [0002] Personal care products such as nursing pads, diapers, sanitary napkins, anti-galactorrhea pads, disposable underwear, etc. are widely used in hospital operations, gynecological examinations, maternity care, child care, and paralyzed patients because of their convenient care and effective prevention of cross-infection , incontinence and mobility-impaired patients, women's menstrual period and other special periods. These care products are usually in direct contact with human skin, so they need to be strictly sterilized and then packaged for transportation. This requires that the outer bags for packaging these care products have excellent barrier, tear resistance and heat-sealing properties. At the same time, in order to protect personal privacy and prevent embarrassmen...
