The change of the frontal tape of diapers has witnessed the rapid development of domestic diapers. Before 2008, the large market share of domestic brands was still dominated by OPP frontal tape coated with release silicone oil. , After 2012, softer non woven Velcro became the mainstream of the market.

1. OPP magic frontal tape

The main material of the OPP magic frontal tape is biaxially oriented polypropylene film, which is transparent, smooth, printed with colorful cartoon patterns, and has high holding force and proper peeling force. The surface is coated with a layer of release silicone oil, which can be pasted repeatedly when used in conjunction with the left and right stickers.

According to the size of the peeling force, it can be divided into mild peeling and heavy peeling. Generally, baby series products use mild peeling (peeling force 2.5-7.0N), while adult series products use heavy peeling (peeling force 5-12N), some In areas where the weather is hotter, the adult series will also use mild peeling.

According to the material of the OPP film, it can also be divided into matt and bright OPP magic frontal tape. The matt type is also called a matte film, which is made by adding matting material to the BOPP material or using a matting roller to make the OPP form a slightly uneven surface, so it is more difficult to coat. Silicone oil, when applying silicone oil at high speed, cannot completely penetrate into the low point. If the pressure sensitive adhesive on the left and right sides of the CPP is used improperly, it is easy to have the problem of adhesive transfer, and the peeling force is too large,so it cannot be torn apart. Some adult moderate to heavy peeling magic frontal tape.

2. Mesh and velvet magic frontal tape

Mesh and suede front and waist tapes are composite materials of fabric mesh or flannel and low weight OPP or PET film. The flannel is compounded with the film, and the printing pattern is usually printed on the film. They are used in conjunction with the Velcro, which can be pasted repeatedly and the tightness can be adjusted freely.

The sticker on the mesh surface is also called hook and loop Velcro. The hook and loop at the free end is hooked together with the mushroom head to achieve a fixed effect on the diaper. The mesh cloth on the mesh surface is low in weight and will not cover the printed pattern of the underlying film, and the pattern is clear. .

The suede sticker is a warp knitted flannel. It is usually necessary to raise the flannel to generate burrs on the surface layer of the flannel, so as to generate enough peeling force to ensure the good fixation of the diaper. The weight is relatively high, and it has a certain degree of coverage for the printed pattern of the underlying film, which will affect the clarity of the printed pattern. Generally, it is more appropriate to design the printed pattern with soft tones.

At present, the technology of the two is very mature and can be matched with the injection hook of any manufacturer.

Mesh and suede Velcro have high holding power and appropriate peeling force, and are generally printed with colorful cartoon patterns.

3.Non woven frontal tape  

he non woven frontal tape is a combined non woven fabric composed of long fiber spunbond non woven fabric or short fiber carded hot air non woven fabric and long fiber spunbond non woven fabric. Specially designed Velcro. Since only non woven fabrics are used, it is softer and less expensive, and has been widely used in recent years. At the same time, with the wide application of flexographic printing process and the design of new embossing, the appearance and color pattern of non woven Velcro embossing are more abundant, and non woven fabrics will eventually fully replace mesh and suede.

Since non woven is denser, the peeling force is relatively small compared to mesh and flannel, so it is necessary to use an optimized injection hook to improve the peeling force of Velcro and non woven Velcro, usually Fm10 is 0.8-2.0N125mm, At the same time, the shear force greater than 30N is generally considered to be safe for use, and it can avoid accidental opening during use or stretching caused by the falling of the diaper after wetting.

With the development of the diaper industry, the closure system of diaper products has also undergone great changes. The closure system includes open diaper OPEN TYPE DIAPER and pant diaper PANTS DIAPER. The pant type closure system is usually an elastic waist composed of spandex and non woven fabrics. The closure system of the open diaper is composed of frontal tape and left and right stickers. By understanding the classification and development status of diaper frontal tape, it is helpful to understand the overall development history of the diaper industry.
