Problems solved by technology

However, the longitudinal elongation of the breathable bottom film produced by the traditional blow molding method usually does not reach 100%. Therefore, the ordinary bottom film of baby diapers and the deep embossed bottom film of sanitary napkins can only be produced by casting or calendering.
However, the initial investment of the casting method and the calendering method is much greater than that of the blow molding method, and the production cost of the bottom film is also significantly higher than that of the blow molding method, which is equivalent to raising the overall price and is not conducive to manufacturers controlling production costs.

Embodiment 1

[0024] A kind of baby diaper, comprising common base film, described common base film is made by blow molding method and with the following components of mass fraction as raw material: 47 parts of metallocene, 3 parts of propylene-based elastomer, 50 parts of calcium carbonate particles , 1.5 parts of maleic anhydride graft compatibilizer. Specifically as shown in Table 3:

[0025] Table 3: Main performance table of 15g ordinary bottom film by blow molding method

[0026]

[0027] It can be seen from the above table that the ordinary bottom film obtained by blow molding using the above raw materials is not only significantly higher than the indicators in Table 1 in terms of air permeability, tensile strength, CD elongation and hydrostatic pressure, but its MD elongation The production rate is also more than 100%. Compared with the base film produced by the existing casting method and calendering method, the production cost is much lower and the process is simpler. Under t...

Embodiment 2

[0029] A sanitary napkin, comprising a deep embossed base film, the deep embossed base film is made by blow molding and uses the following components in parts by mass as raw materials: 45 parts of metallocene, 1 part of propylene-based elastomer, calcium carbonate 50 parts of granules, 1.5 parts of maleic anhydride grafted compatibilizer. Specifically as shown in Table 4:

[0030] Table 4: Main properties of 25g blow molding deep embossed base film

[0031] .

[0032] It can be seen from the above table that the ordinary bottom film obtained by blow molding using the above raw materials is not only significantly higher than the indicators in Table 2 in terms of air permeability, tensile strength, CD elongation and hydrostatic pressure, but its MD elongation The production rate is also more than 100%. Compared with the base film produced by the existing casting method and calendering method, the production cost is much lower and the process is simpler. Under the condition ...

Abstract

The invention discloses an infant paper diaper and sanitary napkins. The infant paper diaper and the sanitary napkins comprise a basic film, wherein the basic film is made by a blow molding method andis made by using the following components in parts by mass as raw materials: 45-47 parts of metallocene, 1-3 parts of propenyl elastomers, 50 parts of calcium carbonate granules and 1.5 parts of maleic anhydride grafted compatilizers. The longitudinal elongation percentage of the basic film of the infant paper diaper and sanitary napkins disclosed by the invention is greater than 100%, and the blow molding method is used for replacing a tape casting method and a rolling method, so that the production cost and the management cost are markedly reduced.

Description

technical field [0001] The invention belongs to the technical field of sanitary products, in particular to a baby diaper and a sanitary napkin. Background technique [0002] Breathable film is an environmentally friendly functional material that is breathable (steam) and water-proof (liquid, bacteria, dust). Embossed base film, etc. [0003] For baby diapers currently on the market, the performance requirements for ordinary bottom films are shown in Table 1: [0004] Table 1: Common base film index of baby diapers: [0005] Weight 15G±1.5g / m 2 Width ≥200,±3mm:<200,±2mm Breaking force (N) Longitudinal MD≥5.5, transverse CD≥1.7 Elongation (%) Longitudinal MD≥100%, horizontal CD≥200% Hydrostatic Pressure Resistance (MBAR) ≥45 Water vapor transmission rate WVTR(g / m 2 *24hr) 1600≤δ≤2800 [0006] . [0007] The performance requirements of deep embossed bottom film for sanitary napkins on the market are shown in Table ...
