READ MOREStand-up pouches have a good seal to keep out air, moisture and light, thus preventing pigments from deteriorating, drying out or being affected by external factors that may change their properties. The stand-up pouches are designed to allow the user to pour or squeeze out cosmetics and pigments, allowing for more accurate control of the amount used per application. Stand-up pouches are able to stand on their own, saving space when storing and displaying and making the layout of warehouses and counters more rational. Cosmetic and pigment stand-up pouches provide better physical protection, reducing the impact of extrusion and impact on cosmetics and pigments during transportation and handling.

READ MOREWhen discussing the material barrier properties of cosmetic and pigment stand-up bags, we have to deeply analyze its technical core and how our company, as a leader in the industry, can rely on a strong R&D team, advanced production equipment and rich industry experience to ensure that the designed and produced stand-up bags can perfectly cope with the challenges of complex chemical components in cosmetics and pigments, achieve efficient barrier, and ensure product quality and consumer safety.
Cosmetics and pigments often contain a variety of chemical components, including but not limited to water, oil, solvents, pigment particles, preservatives, antioxidants and various additives. These ingredients not only require the packaging materials to have excellent chemical stability to avoid chemical reactions that cause the contents to deteriorate, but also have excellent barrier properties to effectively isolate the invasion of air, moisture, light and microorganisms, thereby extending the shelf life of the product and maintaining its color, texture and efficacy.
1. Material selection and modification technology
Our company's R&D team is well aware of this. Through in-depth research on the physical and chemical properties of different materials and their interactions with cosmetics and pigment ingredients, we carefully select and innovatively modify polymer materials such as polyethylene (PE), polypropylene (PP), nylon (PA) and multi-layer co-extrusion composite materials to optimize their barrier properties. For example, the use of high-barrier nylon layer and low-cost polyethylene layer composite can not only ensure excellent oxygen and water vapor barrier properties, but also control costs and achieve high cost performance.
2. Multi-layer co-extrusion technology
We have advanced multi-layer co-extrusion film blowing machines that can accurately control the thickness and distribution of each layer of material to achieve accurate construction of multi-layer structures. This technology enables self-supporting bags to assume barrier, strength, heat sealing and other functions at different levels to ensure the optimization of overall performance. For example, the inner layer that contacts cosmetics or pigments uses low-permeability materials, while the outer layer uses wear-resistant and UV-resistant materials to protect the contents in all directions.
3. Sealing structure and process
The sealing of self-supporting bags is a key link in their barrier properties. We use precision injection molding to manufacture bag opening parts to ensure the firmness and tightness of the sealing structure. At the same time, combined with heat sealing technology, by precisely controlling the heat sealing temperature, pressure and time, we can achieve high-strength sealing of the bag opening, effectively preventing the penetration of air, moisture and microorganisms. In addition, we have also developed unique leak-proof designs, such as reinforced bottom support structure and edge sealing reinforcement, to further improve the overall sealing performance of the self-supporting bag.
Based on a deep understanding of customer product characteristics and sterilization processes, our R&D team can respond quickly to market needs and provide customized self-supporting bag design solutions. Whether it is for the barrier needs of specific chemical components, or considering the appearance, feel and environmental protection requirements of the product, we can achieve the best match through material selection, structural design and process optimization to ensure the high cost performance and excellent performance of the product.
More than half of the company's employees have more than 10 years of experience in the industry. They are not only proficient in packaging material science, processing technology and quality control, but also have keen market insight and innovation capabilities. This has laid a solid foundation for us to continue to launch new products that meet market trends and meet customer needs. At the same time, we have our own laboratories and advanced testing equipment in the industry, which can conduct comprehensive testing of raw materials, semi-finished products and finished products to ensure that product quality meets relevant domestic and international standards.
While pursuing high performance, we also attach great importance to environmental protection and sustainable development. By selecting recyclable materials, optimizing production processes, and reducing waste emissions, we are committed to reducing the environmental impact of products during their life cycle. In addition, we are also actively developing new environmentally friendly materials, such as bio-based materials and degradable materials, to provide more green and sustainable packaging solutions for the cosmetics and pigments industry.
In terms of the material barrier properties of cosmetics and pigments self-supporting bags, our company relies on a strong R&D team, advanced production equipment, rich industry experience and continuous technological innovation to ensure that the self-supporting bags produced have excellent barrier properties, effectively prevent leakage of contents or external contamination, and provide safe, reliable and efficient packaging solutions for the cosmetics and pigments industry.
