Precautions for the production process of high-temperature retort pouches

The commonly used high-temperature retort pouch substrates are PET, NY, AL, RCPP, etc. The corona treatment effect of these substrates directly affects the composite strength of high-temperature retort bags; During the high-temperature cooking process, the substrate shrinks to varying degrees. The corona treatment of the material did not achieve the expected effect, the composite strength was low, and there was not enough force between the composite bag layers to hinder the shrinkage of the substrate, resulting in serious delamination of the bag layer after high temperature cooking. In general, the surface tension of PET and NY used for high-temperature retort pouches should reach 50mN/m, and RCPP should reach 40~42mN/m. In addition, certain additives in the substrate, such as anti-blocking agents, anti-slip agents, and antistatic agents, are released to the surface at an accelerated rate of high temperatures, which can lead to a decrease in adhesion. Since the high-temperature and high-temperature retort pouch is basically in water during the sterilization process, when measuring the matrix shrinkage, the matrix shrinkage should be measured at 120 °C for 30min. The shrinkage rate should be small and stable, especially for BOPA film, RCPP film, SCPP film, and the longitudinal and horizontal moisture-proof shrinkage rate is recommended to be no more than 1.5%, which can be called cooking grade film.

What is high-density polyethylene

High-density polyethylene (HDPE), which is a white powder or granular product. Non-toxic, tasteless, crystallinity of 80%~90%, softening point of 125~135 °C, service temperature up to 100 °C; Hardness, tensile strength and creep are better than those of low-density polyethylene; Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, insoluble in any organic solvent at room temperature, resistant to acid, alkali and corrosion of various salts; The film has low permeability to water vapor and air, and low water absorption; Poor aging resistance, environmental stress cracking resistance is not as good as low-density polyethylene, especially thermal oxidation will reduce its performance, so antioxidants and ultraviolet absorbers must be added to the resin to improve this shortcoming. The heat deflection temperature of high-density polyethylene film is low under stress, so attention should be paid to it when applying.

Parafilm customization process and matters

PP parafilm is widely used in product packaging and sealing in food, cosmetics, daily necessities and other industries, and each user packs a variety of products, so the need for PP sealing film also needs to match, including the specifications, thickness, functional characteristics of PP sealing film, etc. Therefore, in order to meet the different needs of users, the parafilm customization service has been launched, that is, the parafilm is customized according to the needs of users, which has been recognized and praised by the majority of new and old users. The customization process and precautions of PP parafilm are as follows: 1. The thickness of PP parafilm must be determined, otherwise our company has begun to enter production as required, and the loss shall be borne by the user. 2. The quantity/weight of PP parafilm is determined according to the actual needs. The unit is KG, and the MOQ is 100KG. 3. Used for color printing of PP parafilm, determine color, blank, 4 colors, 6 colors, 8 colors, etc. 4. For the original design of PP parafilm, the user must design the graphic information and typesetting of the parafilm and provide it to our customer service. If there are any changes before the draft is finalized, please communicate with the customer in a timely manner. 5. The functional characteristics of PP parafilm, if necessary, should have the characteristics of easy tearing, easy peeling, high temperature cooking resistance, corrosion resistance, freezing resistance, anti-fogging and so on. Freezing, anti-fogging, etc. anti-fogging and other features.

What changes will happen to packaging food labels in the future?

Key point: In recent years, with the continuous emergence of food safety emergencies, people's attention to food labeling has been increasing. Complaints from consumers about information labeling errors on food labels have occurred frequently, which has also attracted the attention of the country to food labeling and labeling. A series of relevant regulations and policies have been introduced to regulate the labeling of packaged food. At the same time, the development of food labeling is also moving towards diversification.

Whether there is a law to follow in the innovation of packaging

When it comes to innovation in domestic food packaging, there is one that has to be mentioned, it is Nongfu Spring. Its products have won the Pentawards, which are known as the Oscars of packaging design, for many times. Nongfu Spring was nicknamed a "design company" by netizens. Not only that, Nongfu Spring's performance is still rising, from 5.2 billion yuan in 2010 to 15 billion yuan in 2016. However, not all companies have achieved this result. Some companies are not small in product innovation, and they also make efforts in products and packaging, but it is difficult to achieve similar performance returns.

The difference between PVC and PE materials, as well as the uses of each material

1. Differences in application; Application of polyethylene (PE): cling film, vest style plastic bags, plastic food bags, buckets, kettles, etc. Application of polyvinyl chloride (PVC): cling film, plastic shoes and leather products, film, cable, plastic bags. 2. Different characteristics; Polyethylene (PE) feels waxy to the touch and is lighter in weight compared to similar plastics, with a certain degree of transparency. Characteristics of polyvinyl chloride (PVC): Hard plastic, commonly used in industrial fields. 3. Differences in material properties; Polyethylene, abbreviated as PE. It is a polymer of ethylene and non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, and good electrical insulation. It is suitable for making packaging materials for food and medicine, making tableware and medical devices, and can also be used as insulation materials for the electronic industry. Polyvinyl chloride, abbreviated as PVC. It is a polymer of vinyl chloride. Polyvinyl chloride (PVC) is a synthetic material with various advantages and is an ideal material for engineering plastics. Good chemical stability, acid and alkali resistance. Moisture resistant, aging resistant, and flame resistant.

3 tips for printing design colors

Whether it's graphic design or web design, color is always the most important aspect. When we are far away from the display screen, what we see is not beautiful layout or beautiful images, but the colors of the webpage. There are many principles of color that we cannot explain one by one here. You can refer to relevant design books for a systematic understanding. Here we just want to tell you some tips for webpage color matching. 1. Use one color. This refers to selecting a color first, and then adjusting the transparency or saturation, so that the page looks uniform and layered. 2. Use two colors. First select a color, then choose its contrasting color. 3. Use a color scheme. Simply put, it means using a sensory color, such as light blue, light yellow, or light green; Or soil yellow, soil gray, soil blue. In webpage color matching, it is also important to remember some misconceptions: 1. Do not use all colors, try to control within three to five colors. 2. The contrast between the background and the previous text should be as large as possible (never use intricate patterns as the background), in order to highlight the main text content.
