Problems solved by technology

[0004] At present, the bottle caps used in the industry and the market are all non-light-blocking, especially the used HDPE material bottle caps for bottle packaging do not have light-blocking properties, and the inventors have found through research that the light-blocking properties of bottle caps have a great influence on the content of the contents. Conservation actually has a big impact

[0032] 1. Preparation of light-blocking masterbatch

[0033] In the present invention, the light-blocking masterbatch is prepared first. The composition of the light-blocking masterbatch of the present invention comprises based on 100 parts by weight of the total weight of the light-blocking masterbatch:

[0034] HDPE resin: 35-40 parts by weight; titanium dioxide: 55-65 parts by weight; polyethylene wax dispersant: 1-3 parts by weight; ester antioxidant: 0-1 parts by weight.

[0035] After putting the above raw materials into a stirring tank and stirring evenly, the mixed material is added into an extruder, and the mixed material is melted and extruded, then pelletized and dried. The bulk density of the obtained light-blocking masterbatch is 1.2kg / m 3 , The ash content is 64-74%.

[0036] In the present invention, products sold on the market can also be used directly, for example, the product of Holland Color Co., Ltd. whose trademark is 473-30-25424.

[0037] 2. Preparat...

Embodiment 1

[0071] Use the light-blocking masterbatch with the brand number 473-30-25424 from Holland Color Company and the HDPE bottle cap raw material with the brand name M430A from South Korea’s Total Company, so that the light-blocking masterbatch can be added to the light-blocking HDPE bottle cap in terms of raw material weight. The content in the bottle is 5% by weight, and the capping machine equipment is used to finally compress and mold through processes such as screw mixing and heating to prepare bottle caps. The finally obtained light-blocking HDPE bottle cap of Example 1 has a weight of 3.3 g and a cap size of 0.95 mm.

[0072] The above-mentioned light-blocking HDPE bottle cap and PET light-blocking bottle body are assembled into a dairy packaging bottle.

[0073] Experiment and evaluation of the influence of bottle caps on the taste acceptability of white milk products

[0074] Put the same white milk sample into the packaging of the control group (non-light-blocking bott...

Embodiment 2

[0099] Except that the content of the light-blocking masterbatch in the light-blocking HDPE bottle cap is 6% by weight based on the weight of raw materials, other conditions are the same as in Example 1.

Abstract

The invention provides a dairy product packaging bottle and a preparation method thereof. The dairy product packaging bottle comprises a bottle body and a bottle cap, wherein the bottle cap is an HDPE bottle cap with light resistance, the light transmittance of the bottle cap within the full-wave band light source range of 200-1100 nanometers is smaller than 0.5%, and the light transmittance of the bottle cap within the visible light range of 200-760 nanometers is smaller than 0.05%. According to the light-blocking dairy product packaging bottle, the taste, flavor and the like of dairy products can be prevented from being affected, the terminal display image can be improved, and the light-blocking dairy product packaging bottle has very excellent practicability in the field.

Description

technical field [0001] The invention relates to the field of packaging bottles for dairy products, in particular to the field of packaging materials for white milk with light-blocking properties. Background technique [0002] Traditional dairy packaging materials are usually in the form of Tetra Pak packaging. In addition to being sterile, this packaging material also has excellent light-blocking, oxygen-blocking, and moisture-blocking properties. However, Tetra Pak packaging has insufficient mechanical strength, a single shape, cannot be opened and closed repeatedly, and is not recyclable. With the rapid development of the beverage industry, these defects are becoming more and more obvious. [0003] Therefore, HDPE (high-density polyethylene), PET (polyethylene terephthalate) plastic packaging and aseptic filling equipment have emerged as the times require, and have been maturely used in milk and other beverage industries, especially in There are abundant studies on the di...
