but can only slow down the microorganisms that need oxygen. If you want to keep the food from spoilage and prolong the shelf life
Special attention should be paid to the food packaging of vacuum pumping. Vacuum pumping can not block the growth of bacteria in the food, you need to treat the food, such as high temperature, Then vacuum the food packaging bag using the sterilizer, which greatly prolongs the shelf life.
Packaging color printing -- the form of non-woven packaging color printing has changed. For example, 6ha1 is changed to 6ha2 to rescue the color printing of non-woven packaging -- the medium-sized bulk container for color printing of non-woven packaging containing damaged packages -- it is suitable for the rigid and flexible movable color printing tank cabinet of non-woven packaging with mechanical loading and unloading volume of 250L ~ 3000l -- tank container, road tank car and railway tank car.
.The types of yarn are divided according to the material: natural fiber: plant fiber: Cotton (cotton) jut line (animal fiber): wool (wool) silk synthetic fiber: nylon (nylon) (polyester, also known as tetron) acrylic (acrylic) polypropylene (PP) polyethylene (PE)
After the iron can enters the oven, the next stage is heating up. The main function is to raise the iron tank from room temperature to the set temperature. After reaching the set temperature, it enters the constant temperature stage, which is to ensure the stability of the set temperature. The function of the cooling area is to fully cool the dried iron cans, but the cooling is not enough. When the iron cans are stacked, the paint films are very easy to be scratched by each other, and the sticking phenomenon is easy to occur after stacking. The baking time has a great relationship with the machine speed. If the machine speed is too fast, the whole drying time will be shortened, the required temperature time will not be sufficient, and the paint to be baked will not be sufficient, resulting in tender paint film caused by poor drying. It makes the food or beverage easy to deteriorate.
.() foreign trade export cartons and 5-layer corrugated boxes are generally used for color printing of external non-woven packaging, and B / C tiles are mainly used for corrugated. The calculation formula of outer box is: (length + width + / 100 x (width + height + / 100 x unit price per square meter).
Warning signs are usually expressed in graphics and words according to the requirements and relevant matters needing attention in the aspects of cargo loading, unloading, storage and transportation.
Warning signs are usually expressed in graphics and words according to the requirements and relevant matters needing attention in the aspects of cargo loading, unloading, drinking utensils water utensils and ritual utensils. The decoration is mainly carving.
Clothes, quilts and other items shall be placed in the bag [2] as far as possible, at least 3-5cm away from the sealing zipper. Large items shall not be put in forcibly.
With a certain amount of stock, this non-woven packaging bag has become the choice of many people.
Home page recommendation.In the drying process, the coating and shall be dried in a tunnel oven. The drying condition of offset printing is usually 130 ℃ ~ 160 ℃, and the time is about 13 minutes. The coating drying strip is between 170 ℃ and 210 ℃, and the tunnel oven is about 25-35m long. It consists of three stages: heating zone, constant temperature zone and cooling zone. These areas are arranged in strict accordance with the requirements. After this stage, the products need to be refrigerated for a period of time to make their hardness better.
Moisture proof materials must be placed flat and hoisted from here to New York. Do not throw. Do not handle perishable materials with care. Fragile materials shall be stored in a dark place and kept dry. Do not throw them flat. Do not heat them upside down. Do not open this end upside down. Be careful. Porcelain inflammables are transported to Canada. The warning signs are based on certain hazard characteristics, such as flammability, vulnerability, etc, Graphics and characters printed on the color printing of non-woven packaging of goods. It can help relevant personnel take protective measures to ensure the integrity of goods and personal safety. Warning signs often printed on the color printing of external non-woven packaging include inflammables, food and beverage and daily chemical industries are sorted out to analyze the order trend of non-woven packaging color printing industry. In terms of the home appliance industry consumer electronics, the product growth of various home appliances was significantly differentiated in August: the output growth of air conditioners, refrigerators and freezers accelerated, the output of washing machines and electric fans declined, and the output of other home appliances remained stable. However, the cumulative year-on-year output of various household appliances is far lower than that of the same period.
A: card suction non-woven packaging color printing refers to the heat sealing of the bubble shell on the surface of the paper card with blister oil. The common supermarket battery non-woven packaging color printing is mostly used. It is characterized by the need for blister sealing equipment to package the product between the paper card and the bubble shell. It should be noted that the surface of the paper card must be coated with blister oil (so that it can be thermally bonded with PVC foam shell); The foam shell can only be made of PVC or pet; Because the bubble shell is only adhered to the surface of the paper card, it is a long-term business of non-woven bag, canvas bag, thermal insulation bag and hand decoration bag & nbsp; Welcome to consult. So the packaged products are not easy to be too heavy.
Research on degradable technology of non-woven fabrics degradable non-woven fabrics can be divided into biodegradable non-woven fabrics and photodegradable non-woven fabrics
Inspection environment.If the machine speed is too slow during baking, it will lead to baking. In this case, many coatings will become brittle, and it is very easy to remove paint or paint during later processing. At the same time, baking will also lead to the discoloration of the coating. The main measures to avoid poor baking are: the temperature of the oven regularly and the curve in the automatic instrument to ensure the temperature and standard time under the standard time.
Folding special care zipper is not smooth: apply candle or leather wax on the zipper to improve the effect.

Non woven packaging bags are used every day for everyone. No matter from which aspect, the effect of the packaging bag is very big. It has become a common and frequent use of the same thing in ordinary days. Everyone is using it almost every day. When using packaging bags we often feel the difference of non-woven bags. This is due to the different raw materials of non-woven bags. In the past, the skills of non-woven bags in production were relatively backward, and the non-woven bags may cause some damage to, but today's non-woven bags are different.
The key to the development of non-woven stabilization technology is the preparation and application of new antioxidants, UV stabilizers and base capture agents. Professional non-woven bag, cotton bag, canvas bag, thermal insulation bag, hand decoration bag & nbsp; And other types of products are complete, selling well at home and abroad, and the equipment has a long service life! Products lead the industry of wire products. Welcome to inquire. Refill non-woven containers for daily chemicals, trays or turnover boxes for food, non-woven stabilization technology and high-quality non-woven products, so as to improve its reuse or recycling value.
