Plastic cosmetic packaging is an important carrier for protecting cosmetics and conveying brand image, and its quality and safety are crucial. Strict testing is essential to ensure the quality and safety of plastic cosmetic packaging. This article will introduce how to detect plastic cosmetic packaging to ensure it meets relevant standards and requirements.

1、 Appearance inspection

Appearance inspection is the first step in plastic cosmetic packaging inspection. By observing the appearance of the packaging, its quality and safety can be preliminarily judged. Appearance inspection mainly includes the following aspects:

Packaging integrity: Check for defects such as damage, deformation, and cracks in the packaging to ensure its integrity.

Printing quality: Check whether the printing patterns and text on the packaging are clear and complete, and whether the colors are bright to determine whether the printing quality meets the standards.

Color and Transparency: Observe the color and transparency of the packaging to ensure the quality of the plastic material.

2、 Size inspection

Size inspection is an important step in ensuring that plastic cosmetic packaging meets design requirements. By using precise measuring tools, the dimensions of the packaging are accurately measured to ensure consistency with design requirements. Size detection mainly includes parameters such as packaging length, width, height, and wall thickness.

3、 Material testing

Material testing is a crucial step in evaluating the safety and environmental friendliness of plastic cosmetic packaging. By conducting chemical composition analysis and physical performance testing on packaging materials, it is possible to determine whether the materials comply with relevant standards and requirements. Common material testing items include:

Chemical composition analysis: detect the content of harmful substances in packaging materials, such as heavy metals, plasticizers, etc., to ensure compliance with relevant regulations and standards.

Physical performance testing: testing the physical properties of packaging materials, such as tensile strength, tear strength, heat resistance, and cold resistance, to evaluate their durability and stability in practical use.

4、 Functional testing

Functional testing is an important step in evaluating the practicality and convenience of plastic cosmetic packaging. By conducting functional testing on the packaging, it can be determined whether it meets the usage requirements. Functional testing mainly includes the following aspects:

Sealing test: Check the sealing performance of the packaging to ensure that cosmetics do not leak or be contaminated by external factors.

Opening test: Test whether the opening method of the packaging is convenient and safe, to ensure that consumers can easily open the packaging.

Durability testing: Simulate actual usage scenarios and conduct drop resistance, pressure resistance, and other tests on the packaging to evaluate its durability in actual use.

5、 Environmental adaptability testing

Environmental adaptability testing is an important step in evaluating the stability and safety of plastic cosmetic packaging under different environmental conditions. By testing the packaging under high temperature, low temperature, humidity and other environmental conditions, its performance can be determined under different environmental conditions.

Plastic cosmetic packaging inspection is a comprehensive process that involves multiple aspects such as appearance, size, material, functionality, and environmental adaptability. Through strict testing procedures, the quality and safety of plastic cosmetic packaging can be ensured, providing consumers with safe and reliable products. As a plastic cosmetic packaging manufacturer, we will continue to strive to improve our testing technology and level, and provide consumers with higher quality and safer packaging solutions.
