In recent years, the awareness of universal health care has injected a strong impetus into the development of the health food industry. The rapid development of the domestic health food industry is accompanied by the dissatisfaction of consumption on quality. From the professional point of view, some quality problems are derived from Health food, but there are many quality problems caused by the quality of health food packaging is not up to standard. Because there is no industry or national standard, which causes the health food enterprises to pay insufficient attention to the quality of packaging, which leads to a series of quality problems.

First, the status quo of health food packaging quality control

Because health foods have specific functions to adjust human functions, they have great similarities with the functions of medicines. China has standardized standards for quality control of pharmaceutical packaging and packaging materials, and it should control the quality of packaging of health foods. Important reference. The health food industry should learn from the pharmaceutical industry's requirements for quality control of packaging materials for packaging quality control. Labthink, as an international provider of testing instruments and testing services, has provided mature testing solutions and testing instruments for the international health care industry. More health food-related enterprises understand the quality control requirements, and introduce the quality control points of health food packaging and introduce them with testing instruments.

Second, health food packaging quality control requirements and instrument introduction

Packaging has an important impact on the warranty period of health foods. Health food production enterprises should control the quality of packaging to “inspect the packaging materials”. In-plant inspection includes testing the tensile strength and elongation at break, surface slip performance, heat seal strength, composite film peel strength, water vapor transmission, and oxygen permeation of packaging materials to ensure the purchased materials. Meet the packaging and production requirements. In addition, the finished product packaging should also pay attention to sealing performance, heat sealing strength, and top air body analysis and testing, so that the enterprise can quickly control the quality from the packaging point of view, and eliminate the accident control caused by the packaging quality problem in the bud.

1, health food packaging and material strength testing items and Instrument Description

Strength is a comprehensive indicator, which is a comprehensive reflection of the tensile strength of the packaging material, the peel strength of the composite film, the heat seal strength, the tear strength, and the puncture resistance. Tensile strength means that the material is subjected to a large stress value of zui before being broken. The detection can effectively solve the damage and breakage of the package caused by the external force due to insufficient mechanical strength of the selected packaging material. Peel strength is also referred to as composite strength or composite fastness. It is used to detect the bond strength between layers in a composite film. If the bond strength is too low, it is easy to cause leakage during interlayer separation during packaging. problem. The heat seal strength is the strength of the seal. During the storage and transportation of the product, once the heat seal strength is too low, the heat seal is cracked and the contents are leaked. Puncture resistance is an indicator of the ability of a package to resist the penetration of hard objects. For the above test items, it is necessary to produce XLW and XLW (PC) series intelligent electronic tensile testing machines through labthink. This type of instrument has the characteristics of strong professionalism and multi-purpose. One instrument can complete the above detection. The preferred instrument for health food companies.

2 , friction coefficient detection and instrument introduction

The friction coefficient test, also known as the slip performance test, is an important indicator for evaluating the slip performance of the inner and outer sides of the health food packaging material, and can be used to evaluate the applicable performance of the machine package. It is tested to ensure that the packaging material has good openness filling properties or can be smoothly conveyed and packaged on a high-speed production line. It needs to be tested by MXD-01, MXD-02, FPT-F1 and other friction coefficient instruments produced by Labthink.

3 , health food packaging materials barrier test control

Barrier performance is two important indicators for oxygen permeability and water vapor transmission of packaging and packaging materials. Among many testing items, the barrier test is also closely related to the shelf life. It is of great significance to the length of the shelf life of health foods and the quality and efficiency of the contents. Detecting the breathability (oxygen transmission rate) of health food packaging and packaging materials can be tested by Labthink's VAC-VBS, VAC-VA, VAC-V2 series differential pressure gas permeation instrument. The product is subject to GB 1038-2000 standard. Products uniformly used by domestic statutory testing organizations. The water vapor transmission test can be tested by W3/030, W3/060, W3/330 and other water vapor transmission rate test systems. These products meet the requirements of ASTM E96, GB 1037- and other standards, and meet the requirements of national standards. It can also be integrated with international testing requirements.

4 , health food sealing performance testing

Sealing performance is an important indicator to be tested after the health food is off the assembly line to prevent quality accidents caused by poor sealing of the package. Sealability refers to the property of the package to prevent other substances from entering or the contents from escaping. There are two methods for commonly used detection methods.

( 1) The MFY-01 seal tester produced by Labthink is tested by the principle of water decompression method. The test procedure is as follows: put a proper amount of distilled water in the vacuum tank, put the sample into the vacuum tank and build it under the pressure plate. The side is completely immersed in the water; then the vacuum pressure and time of the test are set, the test is started, the vacuum chamber is evacuated, the internal and external pressure difference is generated in the sample immersed in the water, and the gas escape in the package is observed, thereby determining the test. Sealing performance

( 2) In-package pressurization method: LSSD-01 leak and seal strength tester is tested by positive pressure method. By applying pressure to the inside of the package, the pressure resistance, sealing degree and leakage index of the health food package are detected, thereby achieving the purpose of detecting the integrity and sealing strength.

5 , top air body analysis

Oxygen is the main factor affecting the shelf life of health food products. The study found that by controlling the proportion of gas components in health food packaging, it can effectively extend the shelf life of products or improve the quality of preservation. However, when the product is filled, a small amount of air will remain in the bottle, so the actual gas composition in the bottle will differ from the expected one, so that the product quality, the expected shelf life validity, and the rationality of the package design are analyzed. Brought difficulties. The HGA-01 Headspace Air Analyzer produced by Labthink can effectively solve the problem of gas component analysis in health food packaging.

In summary, the scientific control and testing methods will provide effective help to ensure the reliability of all aspects of health food packaging. I hope that the above detection methods and methods provided by Labthink will be used in the actual production of health care products. It is helpful to adjust the production process and improve the quality of the products. For more information, please call: Jinan Languang
