If it is not modified PET, the thermal deformation temperature is only 70 degrees, and hot water cannot be filled. It is best not to use it repeatedly, especially under high temperature conditions, DEHP is easy to precipitate, which is harmful to human body. If the pet is modified by alcohol, the thermal deformation temperature can reach 110 degrees and can be filled with hot water. It can also be used repeatedly. When cleaning plastic products, it is best to use neutral detergent and wash the inner wall with flexible things to avoid damaging the plastic surface and causing material precipitation.

If it is a cold drink, it is recommended to use a double PE coated single-layer paper cup, which is thicker and more durable, and the price is a little more expensive than a single PE coated single-layer paper cup. If it is a hot drink, it is recommended to use a hollow cup, which is anti scalding, the cup body is more straight, and the quality is better than a single-layer paper cup. Of course, the price will certainly be more expensive. If there are conditions, the corrugated cup will be more high-grade, more atmospheric and durable. If you want to be environmentally friendly, you can choose PLA coating

PLA coated paper (biodegradable coated paper) itself is a completely decomposable and compostable environmental protection product. Polylactic acid (PLA) is a new biodegradable environmental protection material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Glucose is obtained from starch raw material through saccharification, and then high-purity lactic acid is produced by fermentation of glucose and certain bacteria, and then polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has biodegradable and compostable thermoplastic materials, which take plants as the main raw material source; After extraction, fermentation and polymerization, 100% fully biodegradable materials can be completely degraded by microorganisms in nature into carbon dioxide and water required for plant growth in a composting environment. It has good biodegradability and does not pollute the environment, which is very beneficial to environmental protection. It is a common environmental protection material abroad. Compared with traditional PE coated paper products, PLA coated paper products can be recycled after use. The special and diversified recycling treatment methods of renewable resources greatly reduce the burden of natural resources and environment, which is in line with the endless green cycle criterion. PLA paper cup is the emergence of new technology and new process, which makes the manufacturing technology of paper cup improve continuously. New paper cups will appear and play a greater role in promoting and promoting the design and variety of products. The surface of hot drink paper cup shall be treated with wax spraying or wax dipping. Because cold drinks will cause water on the surface of the paper cup, leading to the softening of the paper cup. It can be waterproof after being coated with wax. The wax is very stable and safe at 0 ~ 5 ℃. To enhance the heat insulation effect and compressive strength of the PLA paper cup, the heat insulation ability of the outer cup body must be enhanced. As long as the surface paper does not show corrugated marks after laminating, the paper with lower gram weight can be used as far as possible; Core paper and PLA paper cup are good. Straw pulp or wood pulp paper with good stiffness and high ring compression strength shall be used. Pulp is processed with some plants as raw materials. It is the basic raw material of papermaking. The plants usually used as pulping raw materials can be divided into four categories: stem fiber, phloem fiber, seed wool fiber and wood fiber. Among them, wood fiber is particularly important.

In fact, the topic of whether disposable paper cups are safe or not has not stopped. Everyone is eager to know the correct answer. What kind of paper cup is safe? Paper cups can be used safely without worrying about its harm to health 1. First, see if the color of disposable paper cup is very white. Don't think that the whiter the disposable paper cup is, the better. The whiter and brighter may add a lot of fluorescent agents. Once these harmful substances enter the human body, they will become potential causative factors. 2.Pinch the stiffness of the cup body. If the cup of fruit juice or beverage is, it is likely that the cup will be deformed and leaked. In serious cases, the paper cup may not end up, affecting the use. When consumers buy disposable paper cups, they can feel the hardness of the cup by gently squeezing both sides of the cup with their hands. The disposable paper cup of Jiangsu Fantasy Packaging New Material Co, Ltd. adopts 340g food grade sun paper. Many experiments have proved that the cup is soaked when poured into the drink, the drink leaks out, the cup cracks and other phenomena, so that consumers can buy it comfortably and use it at ease. 3.If consumers can smell the heavy and heavy ink smell with their nose after they get the cup, or the toxic smell caused by improper storage and moisture of disposable paper cups, the cups should be discarded and not used. If the cup has a serious ink smell, it must not be food grade ink. If it is industrial ink, it contains benzene and toluene. Disposable paper cups are stacked together with 25-100 pieces when packing. If industrial ink is used, the paper cups will be stacked against the inner wall of the cup, which is harmful to health. When the disposable paper cup is poisoned, it will produce mold. The poisonous bacteria will inevitably affect the body of consumers after entering the body through the beverage. The cups ofJiangsu Fantasy Packaging New Material Co, Ltd. are printed with water-based ink, with a shelf life of up to 5 years. The warehouse where the cups are stacked is not wet, with good ventilation equipment, and the cups will not be poisoned. It will not produce ink smell, and it will not affect the taste of drinks because of the cup.

Now people's life is so comfortable. If we don't want to cook, we can order takeout directly and send the takeout box to our home. Generally speaking, it can be heated in the microwave oven. If the material shown above is PP, can it be put in the microwave oven? Can PP be heated in a microwave oven 1. PP material can be heated in the microwave oven. The so-called PP, its Chinese name is polypropylene. Now many microwave lunch boxes are made of this material, which is resistant to high temperature. Even after heating, it will not produce any harmful substances, which is not harmful to human health. 2. At the same time, this material can be reused after being washed, which also requires consumers to check whether there is a sign of PP at the bottom of the lunch box when buying. If you have it, you can buy it. When you come back, you can heat it in a microwave oven. Its heat resistance can reach 130 degrees. What other materials are there in the plastic bottom box 1. If you often order takeout, you need to pay attention to some lunch boxes. Because if it can be placed in the microwave oven, there are generally seven signs, such as PEP, which generally exists in some beverage bottles, but it is relatively disposable. When the temperature reaches 70 degrees, it is prone to deformation, and long-term use will also cause harm to people, so it is not suitable. 2. Another is HDPE, milk bottles, including shampoo at home. These are made of high-density polyethylene, which is relatively safe, but easy to breed bacteria, and don't mind recycling. 3. PVC is also common. For example, some plastic food packages, including children's toys, are made of PVC materials. Some plastic boxes are microwave resistant, with a heat resistance of 80 degrees. However, during the heating process, harmful substances will be released, which will affect the child's development.

A paper cup with exquisite design, excellent creativity and excellent production can add a lot of color to your publicity. The paper cup cover is printed with its own mark and advertisement, which can make people love it. Don't look at a small disposable paper cup, it can bring you unforgettable guests and add color to your life. In recent years, the production of PLA paper cups mostly focuses on safety and environmental protection. Nowadays, people pay great attention to all kinds of food related things and the safety of such special products. PLA paper cup products are a product used by people for water. Therefore, people naturally pay great attention to the safety and environmental protection of disposable paper cup products. Therefore, this has become a matter that disposable paper cup factories should pay great attention to. Jiaxing paper cup the thin thickness of paper cup depends on the number of grams. PLA coated paper (biodegradable coated paper) itself is a completely decomposable and compostable environmental protection product. Polylactic acid (PLA) is a new biodegradable environmental protection material, which is made of starch raw materials proposed by renewable plant resources (such as corn).

Drinks are indispensable in summer. In recent years, the fire belongs to milk tea, but what is the difference between PP milk tea cup and pet milk tea cup? First of all, we need to look at the differences between the two cups. You will easily find that the surface transparency of PP cup is not as good as that of pet cup. The surface of PP cup looks as hazy as fog, while the surface transparency of pet is relatively high. Pet itself belongs to that kind of high transparency cup. From the milk tea cup PP and pet, we can distinguish them from the surface. Secondly, look at the lower diameter of the cup, that is, the bottom. Most of each cup will be printed and engraved with the material used in the cup at the bottom. For example, PP milk tea cup will be engraved with the word PP at the bottom; Pet milk tea cup will be engraved with the word pet at the bottom. So we can judge and distinguish PP cup and pet cup from the bottom of the cup. Look at the digital logo at the bottom of the cup. The digital logo at the bottom of pet milk tea cup is 1, while the digital logo at the bottom of PP plastic milk tea cup is 5.

1. Required customized bag specifications (length * width + bottom width * thickness): the size of raw materials is divided into fixed specifications according to different thicknesses. When we receive the customer's demand, we need to select raw materials according to the specifications, plan the printing area and the weight of corresponding composite materials from the raw materials, and then calculate the layout of the minimum number of batches. 2. Customized bag type consumables: the cutting loss of materials caused by different bag type processes also affects the starting order quantity to a certain extent. In order to ensure complete delivery, after calculating the printing area and the weight of composite materials, we need to consider the proportion of consumables to the whole batch. 3. Since the packaging bags produced in batch must be adjusted and adapted in the actual production process, there will be loss (such as printing color matching, film coating adjustment and bag making calibration), and the actual outbound quantity will have an error more or less (5% - 10%).

Generally speaking, corrugated paper can be classified according to its type: A, C, B, E and their combinations, such as AB, BC, BBC, etc. However, in today's market, there are already finer "F" bars in large-scale use. Another is to classify the base paper according to the number of layers: in this case, it can be divided into two layers of cardboard, three layers of cardboard, four layers of cardboard, five layers of cardboard, seven layers of cardboard, etc; The third is the classification of the shapes. Note that the shapes are not the ones above. As the name implies, the shapes can be classified into U, V, and UV shapes; Generally speaking, the UV shape used in our market is not universal; Fourth: Comparison of corrugated performance: Several flutes/300 mm reduced flat compression strength Edge compression strength A 4.5-5.0 34+2 1.55 4 1 C 3.5-4.0 38+2 1.47 3 2 B 2.5-3.0 50+2 1.36 2 3 E 1.1-2.0 96+2 1.26 1 4 Fifth: Others: Corrugated: Flute; Single corrugated board (also called three ply board): single wall; Double wall; Triple wall;

General packaging products are based on the conventional size of popular products at present. The factory selects common scheme materials (such as kraft paper) for mass production. Some general packaging products do not need to go through gravure printing, so they can avoid unsalable risks and support inventory services. Generally, they are applicable to many scenarios, the starting batch is very low, and even can be distributed on behalf of one piece. Customers only need to buy self-adhesive on the back to package products Then circulation. The general process of customized packaging products is: design → prepress typesetting → plate making → printing → film coating → bag making or cutting (automatic packaging). The most important step is the first step: we evaluate and analyze the customer's brand concept and product value, and design the packaging that fits the enterprise style one-to-one (such as IP characters and VI color system). Custom design can only be used by your enterprise. Try to apply for copyright to avoid infringement. Second, the reason why customers ask how many are required is because they don't understand the principle of printing production. To put it simply, our production process is from printing, film coating to bag making. It is whole film printing, then whole film coating, and finally machine bag making on whole semi-finished film. Therefore, it can not meet the needs of "small sample" or "small batch" put forward by customers. (there are certain standards for equipment operation track, and it is impossible to interrupt any link) About materials: gravure printing materials are facial mask (BOPP, PET, matte, pearlescent, PA, etc.), and the material of the coating process is the intima (PET, VMPET, PE, CP, etc.), and some materials can be used as printing materials or film materials. The specific scheme is analyzed in detail. About links: the semi-finished products after printing and compounding can be put into the bag making machine only after the residual diluent and adhesive are fully volatilized in the small black room of the curing room and meet the national and industrial testing standards. About speed: if the product has more printing color systems, the gravure master takes longer to install the plate roller. The operation speed of printing and film covering equipment is very fast, but the speed of bag making processing is adjusted according to different bag types, specific processes and size specifications, such as octagonal seal and special-shaped bag, which takes longer to make. Therefore, the delivery time usually depends on the gravure plate changing link and bag making processing link.
