How does the CPE frosted zipper bag achieve that uniform and delicate frosting effect?
Publish Time: 2024-11-28
The CPE frosted zipper bag can achieve a uniform and delicate frosting effect, mainly due to its special material selection and fine processing technology.1. Material selectionCPE material: CPE (Chlorinated Polyethylene) is a polymer material with good chemical resistance and weather resistance. The CPE material itself has a certain degree of flexibility and wear resistance, and is an ideal material for making frosted bags.Additives: Adding specific additives to the CPE material, such as frosting agents, antistatic agents, etc., can enhance the frosting effect of the material and the comfort of use.2. Frosting processSurface treatment: The frosting effect of the CPE frosted zipper bag is mainly achieved through surface treatment technology. Usually, physical or chemical methods are used to treat the surface of the material to produce uniform micro-convexities and form a frosted feel.Sanding technology: Common surface treatment technologies include sanding technology. By using fine sanding equipment, the surface of the CPE material is sanded for multiple times, so that its surface gradually forms a fine frosting effect. During the sanding process, the sand particle size and sanding intensity are controlled to ensure that the frosting effect is uniform and fine.Ultrasonic treatment: Some high-end products may use ultrasonic treatment technology, using the high-frequency vibration of ultrasound to finely treat the surface of the material, further improving the uniformity and fineness of the frosting.3. Production processExtrusion molding: The CPE material is first heated and melted by an extruder and extruded into sheets or films. Control the temperature and pressure during the extrusion process to ensure the physical properties and appearance quality of the material.Printing and coating: Printing and coating are performed on the molded CPE material to increase the beauty and functionality of the bag. The printing and coating process needs to be coordinated with the frosting effect to avoid affecting the fineness of the frosting.Cutting and processing: The surface-treated CPE sheet or film is cut and processed to form the final zipper bag shape. Maintain the uniformity of the material during cutting and processing to ensure that each bag has a consistent frosting effect.4. Quality controlMulti-point inspection: Multiple quality inspection points are set up during the production process to conduct real-time inspection of the frosting effect of the material. Specialized measuring instruments such as gloss meters and microscopes are used to ensure that the uniformity and fineness of the frosting effect meet the expected standards.Sampling inspection: Sampling inspection of the produced CPE frosted zipper bags, including appearance inspection, feel test and performance test, ensure that each batch of products meets the quality requirements.
CPE frosted zipper bag achieves a uniform and fine frosting effect by selecting suitable materials, fine frosting process and strict quality control. This bag is not only beautiful in appearance and comfortable in touch, but also has good durability and practicality, can meet various packaging needs, and improve the overall quality and user experience of the product.
