Today we come to know another kind of packaging bag-self-supporting spout bag
The stand-up pouch originated from the French company Thimonier. In 1963, Mr. M. Louis Doyen, the CEO of France’s Thimonier company, successfully applied for a self-supporting pouch patent, which was widely recognized in the US market in the 1990s. Popularize in the world.
Doypack refers to a flexible packaging bag with a horizontal support structure at the bottom and a nozzle on the top or side; the structure is mainly divided into two parts: the nozzle and the self-supporting bag. The stand-up pouch is identical in structure to the ordinary four-sealed stand-up pouch, but composite materials are generally used to meet the packaging requirements of different contents. The nozzle part can be regarded as a general bag mouth hot straw. The two parts are tightly combined to form a beverage package that supports smoking, and because it is a flexible package, there is no difficulty in smoking, and the content is not easy to shake after sealing, which is a very ideal new beverage package.
Advantages of self-supporting spout bag:
1. Strong and firm, tensile and abrasion resistant;
2. It has good airtightness, can effectively avoid light and moisture, and extend the shelf life of the product
3. Exquisite printing, improve product quality and strengthen the visual effect of shelves
4. The bag has strong heat sealing fastness, pressure resistance, drop resistance, not easy to break and leak. Can replace the bottle to use, save costs for you, and improve the competitiveness of the product in the market.
5. With suction nozzle and zipper, it can be used repeatedly, with strong sealing, easy to store, suitable for manual and automatic filling and sealing
6. Effectively reduce the volume, more convenient to carry, and convenient to use.
The advantages of the spout bag make it a unique advantage in the packaging of juice, dairy products, health drinks, and jelly foods. Self-supporting nozzle bag packaging is mainly used in juice drinks, sports drinks, bottled drinking water, smokable jelly, condiments and other products. In addition to the food industry, some products such as detergents, daily cosmetics, and medical supplies are also used. Gradually increase. The self-supporting spout bag is more convenient for pouring or sucking the contents, and can be re-closed and reopened at the same time. It can be considered as a combination of the self-supporting bag and the ordinary bottle mouth. This kind of self-supporting pouch is generally used in daily necessities packaging for liquid, colloidal and semi-solid products such as beverages, shower gels, shampoos, ketchup, edible oil, jelly, etc.
What is the safest and non-toxic material for the spout bag?
The special printing of liquid spout bags used for packaging milk, red wine and other liquids is a packaging method developed over the years. In addition, the development of liquid packaging bags with high temperature cooking is faster, such as right or wrong milk PE film packaging bags, etc. . So, how to judge the quality of liquid packaging film?
(1) The static and dynamic friction coefficient of the nozzle bag packaging film should be low, usually between 0.2 and 0.4, so that it can be filled in a short time on the high-speed filling and packaging machine; the friction coefficient is high and the filling speed is low. Packaging plan , The filling will be short in a short time.
(2) The surface printing fastness of the milk packaging film should be good, it should be resistant to pasteurization and hot filling, and it should be ensured that the ink does not fall in the storage environment at -20°C. Since (1) and (2) are two mutually hostile functional requirements, ink and color masterbatch should be selected accurately for this purpose. To
(3) It has excellent heat-sealability and printability, which can fuse the bag smoothly. Assuming that the resin is too viscous in the formula, the resin melt will stick to the heat-sealing blade during heat sealing; if too much slip agent is used in the formula, the heat-sealing strength will not be high and it is easy to open the warehouse. Satisfying all three requirements is a good liquid packaging bag.
(4) It is resistant to acid, alkali and impact.
(5) The high temperature resistant membrane must be able to survive the sterilization treatment at 121°C for 30 minutes.
(6) The beverage spout bag must have sufficient strength and will not be torn off under the pulling force of the high-speed active filling machine. Function: It is made of non-toxic materials and has the characteristics of acid resistance, alkali resistance, abrasion resistance, good transparency, good gloss, strong anti-fouling power, non-fading, and non-fragmentation, high-temperature molding and radiation sterilization, so as to be sterile , Non-toxic and odorless. It can be used instead of bottles to save costs and advance the competitiveness of the commodity market. Add suction nozzle, reusable, strong sealing, easy to retain, suitable for craftsmanship and active filling and sealing.
