The release paper comprises a bottom paper layer, an adhesive layer, a plastic layer, a transition layer, and a release layer; a hot melt adhesive raw material comprises polyester polyol, diisocyanate, polyether polyol, and a plurality of additives; and a TPU raw material comprises polymer polyol, 1,4-cyclohexane-diisocyanate, a chain extender, and a plurality of functional additives. According to the present invention, innovations are conducted on raw material components of the release paper, the hot melt adhesive, and the TPU film, and extrusion shaping is conducted by utilizing the hot melt adhesive with strong plasticity and the TPU thin film; and the prepared sewing-free TPU leather has the technical advantages of firm adhesion, durability, environmentally-friendly materials, no invisible harm to human body, and the like.

Disclosed is a manufacturing method for an ultrathin white covering film. The ultrathin white covering film includes a protecting film, a white ink layer, an adhesive layer and a release material, wherein the manufacturing method for the ultrathin white covering film includes the following steps: S101: preparing white ink and an adhesive; S102: coating the white ink on the protecting film and drying to form a white ink layer; S103: coating the adhesive on the white ink layer and drying to form a adhesive layer; S104: compounding the release material on the adhesive layer and coiling under certain compound temperature and compound pressure; and S105: curing to obtain the ultrathin white covering film. The present invention reduces a polyimide film layer, reduces a use part from three layers to two layers, can greatly reduce the thickness of a product, make an appearance of the product better, and greatly reduces the price.

To provide a half-cut double-sided tape from a double-sided tape with a release-liner by means of a simple process without contacting a cutter blade directly to an adhesive layer when making the half cuts in the half-cut process. A processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner; a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length are held on the release liner; a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer. A cut trace has a fully cut region in the width direction of the double-sided tape on the release liner and a non-cut region in the width direction of the protect release paper tape, so that the peeling is facilitated.

A soft toy repair device is provided as a non-toxic and pet safe recyclable patch operative to secure tears in an outermost surface layer of soft or plush toys, and pet toys in particular, via adhesion. Such patch comprises an at least partially translucent, flexible tape having backing layer and an adhesive layer, the backing layer having a top side and a bottom side, the adhesive layer applied to the bottom side of the backing layer. A soft toy repair system further comprises a release liner operative to preserve the adhesive layer, which may be a pet-safe, non-toxic and pressure sensitive rubber adhesive, until use. As configured, the patch is operative to remain in place even when subjected to pet play and rough handling.

In the present invention, compounding an addition-reaction-curable organopolysiloxane composition with a specific amount of an organopolysiloxane compound that has three or more (meth)acryl groups in the molecule and a weight-average molecular weight of 1,000 or greater yields an organopolysiloxane composition for use in a release paper or release film in which addition reactions can occur using a small amount of platinum family metal catalyst, cured films can be formed having a peeling strength approximating levels encountered in the past, and addition-reaction-prompted curing will proceed even on a base material containing a catalyst-poisoning component.

The present invention provides a producing method of a part with adhesive and a part with adhesive produced by the method. The producing method includes: a printing process of applying, by printing, the adhesive 20 which does not express adherence property on at least a portion of a surface forming the part from the base material 1; an ultraviolet irradiation process of irradiating, the base material 1 with ultraviolet 2 to make the adhesive 20 express adherence property; an release paper pasting process of pasting release paper on the base material 1; and an outward form pressing process of punching an outer form of the part. The adhesive is previously adhered to the part before it is punched out from the base material 1, and thus, the adhesive can be adhered to the plurality of parts by one positioning operation, and the productivity can be enhanced.
