1. Raw material selection and preparationThe main raw materials of PE coated paper include paper and PE plastic particles. The selection of paper should be based on its characteristics such as strength, smoothness and water absorption to ensure that it is firmly bonded to the PE film and is not easy to peel off. PE plastic particles should be selected according to the product use, such as food grade, industrial grade, etc., to meet different performance and safety requirements. During the raw material preparation process, the paper needs to be pre-treated, such as cleaning, drying, etc., to remove impurities and moisture on the surface and improve the bonding force with the PE film. At the same time, PE plastic particles also need to be screened and dried to ensure their purity and melting performance. 2. Melt extrusion and coatingMelt extrusion is a process in which PE plastic particles are heated to a molten state and then extruded into a thin stream through a screw extruder. The key to this step is to ensure the uniformity and stability of the melting of PE plastic particles. Heating temperature is a key factor affecting the melting state of PE plastic particles. If the temperature is too low, the PE plastic particles cannot be fully melted, affecting the extrusion effect; if the temperature is too high, the PE plastic particles may decompose and produce harmful substances. The speed, pressure and other parameters of the screw extruder will also affect the melting and extrusion effects of PE plastic particles. During the melt extrusion process, it is necessary to regularly detect the melt quality of PE plastic particles, including melt uniformity, viscosity and other indicators. Coating is a process in which a thin stream of molten PE plastic is evenly coated on the surface of the paper. The key to this step is ensuring uniformity and consistency of coating. If the coating speed is too fast, the thin stream of PE plastic may not be evenly coated on the paper surface, causing problems such as missed coating and thin coating. If the coating speed is too slow, the production efficiency may be reduced. Coating thickness is an important factor affecting the performance of PE coated paper. During the coating process, the coating quality needs to be checked regularly, including coating uniformity, coating thickness and other indicators. 3.

Disadvantages of paper cup fansWeaker wind power: Compared with some large fans or high-power handheld fans on the market, the wind power of paper cup fans is generally weaker. This is mainly due to its small size and limited motor power. Therefore, in hot weather or high-temperature environments, paper cup fans may not be able to meet the cooling needs of users.Louder noise: Because paper cup fans usually use high-speed rotating motors and fan blades to generate wind, they will produce a certain amount of noise during their work. Although the noise level varies depending on product design and manufacturing process, in general, paper cup fans are generally noisy and may have a certain impact on the normal use of users.Short lifespan: Due to the uneven quality of core components such as motors and circuits of paper cup fans, some low-quality products may have short lifespans. In addition, since the paper cup fan may be affected by external forces such as collision and falling during use, it may also be easily damaged or malfunctioned. Therefore, when purchasing paper cup fans, users need to choose regular brands and reliable channels to ensure the quality and lifespan of the product.Single function: Compared with some handheld fans or desktop fans with multiple functions, the function of paper cup fans is relatively single. In addition to basic functions such as cooling and lighting, paper cup fans lack other additional functions, such as aromatherapy, humidification, etc. This means that paper cup fans may not be able to meet the needs of users in some specific scenarios.As a portable and uniquely designed small fan, the paper cup fan has the advantages of mini design, energy saving and environmental protection, safety, reliability and multi-function. However, its shortcomings such as weak wind power, loud noise, short lifespan and single function also require users to pay attention when using it. When choosing a paper cup fan, users need to weigh its advantages and disadvantages based on their actual needs and budget, and choose a product that suits them.

Brown kraft paper, as a common packaging and printing material, is widely used in various industries because of its toughness, durability, environmental protection and recyclability. However, to maintain its high-quality properties, proper storage is essential.1. Selection of storage environmentThe storage environment of brown kraft paper must meet certain conditions. Specifically, a cool, dry, and well-ventilated warehouse should be selected as a storage location. The warehouse should maintain constant temperature and humidity and avoid direct sunlight and moisture. The temperature is controlled between 20°C and 30°C, and the humidity is controlled between 60% and 65% to ensure the stability and quality of the paper.2. Storage device configurationThe shelves should have strong load-bearing capacity to cope with the stacking of large amounts of paper. According to the weight and stacking height of the paper, select the appropriate shelf material and structure to ensure that the shelf will not be deformed or damaged when fully loaded. Shelves should have good stability and be able to resist impact and vibration from external forces. Ensure that the shelves will not collapse or shift during operations such as handling and stacking. Choose the appropriate shelf size based on the size of the warehouse and the specifications of the paper. The height, width and depth of the shelves should be able to accommodate the stacking of paper and leave a certain amount of space for easy operation. In order to avoid direct contact between paper and the ground, moisture-proof mats or wooden boards should be laid at the bottom of the shelves. The moisture-proof mat or wooden board should have good moisture-proof properties and can effectively isolate the impact of ground moisture on the paper. Choose materials with good moisture-proof properties to ensure that the paper does not get damp during storage. The moisture-proof mat or board should be flat and without ridges to ensure that the paper stays flat when stacked. Uneven floors can cause the paper to deform or wrinkle, affecting the quality of the paper.3. Implementation of storage methodsPackaging and Stacking: Brown kraft paper should be properly packed before storage. Packaging materials should be waterproof, moisture-proof, and dust-proof to ensure that the paper is not affected by the external environment during storage. When stacking papers, be careful to keep them flat and neat and avoid folding or squeezing. At the same time, the stacking height should be moderate to avoid excessive pressure and deformation of the paper.Protective measures: Necessary protective measures should be taken during storage. First of all, you should regularly check whether the doors and windows of the warehouse are intact to prevent the intrusion of outside air, dust and pests. Secondly, during the rainy and humid seasons, ventilation and moisture-proof measures should be strengthened to prevent the paper from getting damp due to excessive humidity in the warehouse. In addition, during the rainy season and high temperature season, special attention should be paid to observing changes in the paper, and possible problems should be discovered and dealt with in a timely manner.Fire safety: Since paper is flammable, warehouses storing brown kraft paper should have good fire protection measures. Warehouses should be equipped with fire extinguishers and other fire-fighting equipment, and fire drills and training should be conducted regularly. At the same time, smoking and the use of flammable items such as open flames should be strictly prohibited in the warehouse to ensure safe storage.4. Strengthening of storage managementIn order to ensure the storage quality of brown kraft paper, storage management needs to be strengthened. Specifically, a complete storage management system and process should be established to clarify various storage requirements and measures. At the same time, warehouses should be inspected and maintained regularly to ensure the integrity of storage equipment and the stability of the storage environment. In addition, a paper quality monitoring mechanism should be established to regularly inspect the quality of stored paper to ensure that the quality of the paper meets the requirements.
