Embodiment 1

[0050] as attached figure 1 As shown, a high-strength air bubble film includes a base film 1 and a blister film 2 that are attached and fixed. The plastic-absorbing film 2 is distributed with a plurality of blister-forming cylindrical bubbles 21. The shape and distribution of the bubbles 21 under actual production can be determined according to the actual situation. It is not the invention point of the present invention, so no further elaboration will be made here. .

[0051] The bottom film 1 and the blister film 2 are made of modified PE. Modified PE contains the following raw materials in parts by mass:

[0052] LDPE 23-28 parts,

[0053] LLDPE 47-55 parts,

[0054] HDPE 22-26 parts,

[0055] 1-3 parts of opening agent,

[0056] 3-6 parts of sorbic acid,

[0057] 4-5 parts of flame retardant,

[0058] 6-7 parts of stripping liquid.

[0059] LDPE is low-density polyethylene, selected from China Shipping Shell's 242OK product and Saudi Arabia's SABIC brand LD160AT pr...

Embodiment 2

[0085] A high-strength air bubble film, based on Example 1A, the difference is that the stripping liquid is water, the parameter of raw material consumption is the same as that of Example 1A, and the air bubble film is produced according to the production process of the air bubble film in Example 1.

Embodiment 3

[0087] A high-strength air bubble film, based on the basis of Example 1A, the difference is that the amount of stripping liquid is zero, and the parameters of the amount of other raw materials are the same as in Example 1A, and the air bubble film is produced according to the production process of the air bubble film in Example 1 .

Abstract

The invention relates to a packaging material for preventing pressure, moisture and shock, and discloses an air bubble film with good mechanical properties. The air bubble film with good mechanical properties includes a bottom film and a blistered film which are attached and fixed to each other, a plurality of air bubbles formed by blistering are distributed in the blistered film, the bottom filmand the blistered film are respectively made of modified PE, and the modified PE is prepared from, by mass, 28-30 parts of LDPE, 43-52 parts of LLDPE, 20-23 parts of HDPE and 4-5 parts of a flame retardant; and a plastic lubricant is a treated seashell powder with a particle size of 0.4 + / - 0.1 [mu]m, the treated seashell powder is prepared by soaking of seashell powder in a soaking solution, lowtemperature treatment for 10-11 min, drying and screening, the soaking solution is an aqueous solution containing 4 wt% of urea and 8 wt% of NaOH or KOH, and the low temperature treatment temperatureis -15 to -14 DEG C. The plastic lubricant is strong combined with polyethylene, so the strength of the air bubble film is improved.

Description

technical field [0001] The invention relates to a pressure-proof, moisture-proof and shock-proof packaging material, in particular to an air bubble film with good mechanical properties. Background technique [0002] Bubble film, also known as air cushion film and air bead film, is a pressure-proof, moisture-proof and shock-proof packaging material used for packaging filling. Existing bubble film products use high-pressure polyethylene as the main raw material, add whitening agent, anti-blocking agent and other auxiliary materials, form polyethylene film through high-temperature melting and extrusion, and then form bubbles by forming two layers of polyethylene film attached. The purpose of adding the anti-blocking agent is to make the two-layer polyethylene film absorb and form the bubble area to separate smoothly. Existing anti-blocking agents include talcum powder and diatomaceous earth used in the early stage, organic oleic acid amide, erucamide and EBS derivatives used i...
