Which is safer, the composition of sanitary napkins, PE film or release liner

PE film is safer.

The molding film is to coat the silica gel release agent on the surface of the environmentally friendly material PET, PE and OPP film, so that it can show extremely light and stable release force for various organic pressure sensitive adhesives. Different organic pressure-sensitive adhesives such as hot melt adhesive and acrylic.

Glue and rubber systems for pressure sensitive adhesives, etc., required release films.

The release force is different, the viscosity of the adhesive to be isolated from the needle is different, and the release force is adjusted accordingly to achieve a very light and stable release force when peeling.

The PE release film is coated with a release agent, which has the property of not being bonded, and the sticky object cannot be bonded on it, and is mainly used for double-sided tape.

of isolation, as well as label liners, etc.

The low-viscosity glue coated with PE protective film is low-viscosity but still has a certain viscosity and is used to protect the surface of the material.

Yes. PE film is generally found in the following places:

Surface layer (commonly PE perforated film): direct contact with the user**.

Forced diversion layer: conducts the liquid laterally, increases the absorption area, and prevents the concentrated absorption of the liquid The function of the leakage layer: prevents the penetration of the liquid. (Not sure whether LDPE, LLDPE, MLLDPE belong to PE film).

Main materials: LDPE, LLDPE, MLLDPE, PA and other materials are cast films, which are non-stretching and non-directional flat extruded films produced by melt cast quenching. Compared with blown film, it is characterized by fast production speed, high output, and good film transparency, gloss, and thickness uniformity.

At the same time, because it is a flat extrusion film, the follow-up process such as printing, composite, etc. is very convenient, multi-layer co-extrusion cast film can generally be divided into three layers: heat sealing layer, support layer and corona layer, which is wider than the single-layer film in the selection of materials, and can be selected separately to meet the requirements of each layer, giving the film different functions and uses. Among them, the heat sealing layer should be heat sealed, which requires a low melting point of the material, good hot melting, wide heat sealing temperature, and easy sealing; The support layer plays a supporting role in the film and increases the stiffness of the film; The corona layer should be printed or metallized, which requires a moderate surface tension, and there should be strict restrictions on the addition of additives.

During menstrual holidays, use soft and breathable sanitary napkins ufresh.

The "PE perforated film" used on sanitary napkins can prevent menstrual blood from infiltrating and keep it dry; The dryness of the sanitary material is related to the opening ratio of the perforated film, the larger the opening ratio, the higher the efficiency of the liquid to the core layer of the sanitary absorption product, however, in the case of the opening rate of the perforated film is too large, the liquid is absorbed by the core layer and is subjected to the action of human body pressure, there is a situation of reverse osmosis to the surface, and the liquid that is reversed to the surface layer is also more. The opening rate of the perforated film is too small, and the sanitary absorption products can not quickly absorb the body fluid, which is easy to cause side leakage, and the air permeability and moisture permeability of the sanitary absorption products are poor, resulting in the decline of the wearing comfort of the sanitary absorption products. Therefore, a suitable perforated membrane can prevent menstrual blood from infiltrating back and keep it dry.

PE is polyethylene.

In layman's terms, it's plastic.

PE film is generally found in:

1. The surface layer is in direct contact with the user.

2. Forced diversion layer, the liquid is transversely conducted, the absorption area is increased, and the liquid is prevented from being absorbed in a concentrated manner.

3. The role of the leak-proof layer prevents liquid leakage.
