What issues need attention regarding packaging material procurement for cosmetic OEM processing?

Cosmetics OEM When purchasing cosmetic packaging materials, be sure to pay attention to these eight issues

Savvy cosmetic manufacturers know that in addition to raw materials, cosmetic packaging materials are equally important transparent

Packaging materials are not just containers; they also relate to product promotion and product quality, so cosmetic companies must attach great importance to the selection and purchase of packaging materials. Specifically, the focus is on controlling 8 aspects:

1. Packaging material is "compatible"?

The "Cosmetics Safety Technical Specification (2015 Edition)" stipulates that packaging materials in direct contact with cosmetics should be safe, not undergo chemical reactions with cosmetics, and not migrate or release toxic and harmful substances that are detrimental to human health For example, heavy metals in metal packaging, plasticizers in plastic bags, and bisphenol A and its derivatives, if dissolved into cosmetics that are in direct contact with them, pose a threat to both cosmetic quality and human health Therefore, compatibility testing of packaging must be carried out to avoid unnecessary losses

2. Cosmetic packaging printing quality is up to standard ?

Cosmetic packaging requires exquisite printing and good visual aesthetics, so its printing quality inspection is particularly important Currently, routine cosmetic packaging printing quality inspection items mainly include print ink layer abrasion resistance (scratch resistance), ink adhesion fastness, and color discrimination testing. A qualified product is one where no ink shedding or ink detachment occurs during the testing process

3 Cosmetic packaging Is the design reasonable? ?

For businesses, while considering costs, market expectations should be given greater consideration. It's crucial to control the packaging material design, from container shape to label copy, from style positioning to transportation risks, from inner packaging to outer packaging, etc., taking everything into comprehensive consideration Especially concerning the market characteristics and potential of the product, and the basic situation of the consumer group, such as: age, economic income, and cultural literacy of the consumer group. A good product without a suitable appearance will ultimately damage the overall image of the product

4 Packaging Is the capacity standard?

There are many types of skincare product packaging materials, and the process is relatively complex. Sometimes, there are inevitably discrepancies between the container capacity and design standards. Therefore, before container production, the characteristics of the material should be fully considered and specifically controlled. This includes ensuring complete specifications, aesthetically pleasing appearance, and comfortable visual appeal Many companies, when negotiating business, often only know to produce according to the sample, but this is incomplete, because with different materials, the same container will have different net contents

5. Is the packaging temperature-resistant?

Some cosmetic inner packaging is made of composite film, which uses adhesive to bond films of different materials together. Since different materials have different shrinkage rates, when the temperature changes (whether high or low), the composite film bag may show phenomena such as delamination and surface wrinkling. Therefore, temperature resistance testing must be performed on flexible packaging

6. Is the heat seal edge quality durable?

Heat seal strength is one of the important indicators for measuring packaging quality 。 Flexible packaging requires the seal to have a certain strength and tightness, capable of withstanding the pressure of a certain weight of filler, ensuring that the package does not crack or leak during transportation

( 1) Inspect sealing performance

Use an ultrasonic seal tester or vacuum method to observe the sealing performance of the flexible packaging bag's heat-sealed edge

(2) Inspect heat seal strength

When testing heat seal strength, samples of the same width should be cut perpendicularly from the heat-sealed area of the flexible packaging bag. Then, secure both ends of the strip sample to a tension tester and subject it to stretching on a fixture to calculate the maximum force value that causes failure at the heat-sealed area

It should be noted that in addition to the tensile strength of the empty packaging material, the impact of the contents on the heat-sealed area must also be considered

(3) Inspect compression strength

The compression strength of flexible packaging can be tested using a press. Place the sample containing the contents on the sample stage, slowly apply pressure to the desired level, and maintain it for 15 seconds. If no seal edge rupture occurs, it is considered qualified. The amount of pressure applied depends on the situation, as different end-user companies and products may have different requirements

6. Is the package tear opening smooth?

Most facial mask packaging bags come with a wedge-shaped easy-tear opening. When consumers open the product, the opening process must be smooth

It should be noted that during tear testing, the clamping force applied to the material must be sufficient to prevent the material from "slipping" phenomenon during the test. However, when consumers actually open flexible packaging bags, if the force is not applied correctly, a "slipping" phenomenon due to insufficient grip can often lead to difficulty in opening Therefore, when designing packaging, packaging designers must comprehensively consider these properties of flexible packaging materials to find the best solution

7. Is the copy standardized?

The state's regulation of cosmetic labels is very strict; they must be implemented strictly according to standards, especially for characteristic products, where some ingredients and their indicators cannot have the slightest error or discrepancy, otherwise, even the best packaging materials cannot be used. Furthermore, regarding product efficacy, it is crucial to carefully deliberate and review to avoid false content, prohibited words, and consumer ambiguity

8. Defective products proportion exceeds standard ？

Cosmetic packaging materials, especially outer packaging materials like paper boxes and handbags, are often produced manually. Due to the low level of automation, defects or substandard products inevitably occur

Glass bottles, hoses, etc. produced by some machines may also have various problems in terms of color difference, missing print, and shape, so these issues must be considered when purchasing. If the ratio of qualified products to defective products does not exceed the basic standard during packaging material inspection, then the selection of packaging materials is successful. However, when ordering packaging materials, the quantity should be appropriately increased to ensure sufficiency and allow for selection.
