Semitransparent flexible extrusion-blow-molded bottle and preparation method and application thereof

Abstract

The invention discloses a semitransparent flexible extrusion-blow-molded bottle and a preparation method and application thereof. The manufacturing material of the semitransparent flexible extrusion-blow-molded bottle is formed by mixing PP, PP-based elastomer and LLDPE and is a multi-component blended material, and the extrusion-blow-molded bottle obtained and molded by the material has the translucence and flexibility and is easy to mold and low in material cost. The extrusion-blow-molded bottle obtained and molded by the material has the advantages that the better transparency is achieved, the light transmittance of the product is 55%-65%, the more flexible hand feeling is achieved, the flexibility of the product is good, and the expected effect is achieved; except that the transparency and flexibility are achieved, the compatibility among the materials is better, and the properties of the product are guaranteed. Meanwhile, according to the semitransparent flexible extrusion-blow-molded bottle, the material can be molded in conventional extrusion blow molding equipment, and mass production can be achieved. The semitransparent flexible extrusion-blow-molded bottle can be applied to products which require that the internal contents can be seen from a package bottle or applied to products of which the contained sticky contents can be easy to be out only by extruding.

Description

technical field [0001] The invention belongs to the technical field of plastic materials, in particular to a translucent soft squeeze-blow bottle and a preparation method and application thereof. Background technique [0002] In order to obtain a softer effect on the bottle body by squeezing and blowing, LDPE is generally added, but LDPE has poor transparency, and generally translucent materials with good transparency, such as PP materials, are relatively hard. There are some special materials that can meet the requirements in both aspects, but they are not extrusion-blow-grade materials, and they are expensive, so they cannot be added too much, and even require a special machine for molding, which is not very practical. [0003] Generally, it is difficult to balance the transparency and softness of the bottle made of extrusion blowing material. The side of the material that meets the requirements is more expensive, which limits its use effect, or there are difficulties in m...

AI Technical Summary

Problems solved by technology

[0002] In order to obtain a softer effect on the body of the extrusion blow bottle, LDPE is generally added, but the transparency of LDPE is poor, and the translucent material with good transparency, such as PP material, is relatively hard.

There are some special materials that can meet the requirements in two aspects, but they are not extrusion-blown grade materials, and the price is relatively expensive, so you can’t add too much, and even need a special machine for molding, which is not very practical

[0003] Generally, it is difficult to balance the transparency and softness of bottles made of extruded blown materials. The side with materials that meet the requirements is more expensive, which limits its use effect, or has difficulties in molding, which are all caused by the properties of the materials.
