Functional adhesive available

In the 1990s, bagging was still a novelty for many beverage and food manufacturers around the world. Although beverage bags have been used, this application is still selective. Today, such packaging is no longer seen as a rarity. In North America alone, more than 4 billion beverage bags are produced in one year. European production equals or even exceeds this number. In addition to beverages, this innovative form of packaging has also won the packaging of other areas such as pet food, leisure, meat, salted snacks, and even fertilizers and pool chemicals.
This popularity shows the benefits of the bagging method: light, which means it is superior to rigid packaging in storage and transportation. A truck's flexible packaging, such as a bag, is equivalent to a three-truck rigid packaging material. For the user, there are also advantages such as easy opening, easy labeling, easy-to-install and re-closed zippers, and fascinating in terms of size, shape, and pattern. However, rigid packaging is an impossible choice.
The main squeezing technique for bagged packaging is in the compounding of the film and the structure of the bag. The world famous adhesives manufacturer Rohm and Haas is now meeting these composite and structural requirements with its adhesive products and services. The adhesive technology can be developed for its bagged customers in terms of membrane technology, performance, and the structure and filling techniques of the bag.
Rohm and Haas has succeeded in keeping up with emerging membrane technologies such as high slip coating technology. Tool makers are now using it to maintain filling and packaging at line speeds of 200 per minute. It is expected to reach 500 per minute in the future. Rohm and Haas adhesives can be firmly bonded to the film, even if they interact with the slip agent. Slip agents are used to maintain a low coefficient of friction to help achieve high speed packaging. The company's wide range of products can maintain its close adhesion in subsequent molding, filling and packaging.
Ink is another key area of ​​scientific research and development of the company, because a large proportion of composite materials are used in flexible packaging, so that the ink will be in direct contact with the adhesive system.
Adhesives and inks react for three main reasons: the solvent held in the ink or adhesive; the compatibility of the ingredients in the ink or adhesive; the mechanical power of the laminator and slitting. These interactions also vary with some minor variations such as the color of the ink. The way to reduce these interactions is to increase the weight of the adhesive coating to accommodate ink coarse particles or to slightly adjust the color to increase the bonding strength.
With the popularity of bags, there have been many trends in innovative applications. For example, hot filling and sterilizability are two rapidly growing directions in bagged applications. Hot filling is becoming popular because low viscosity helps increase filling speed and line speed; specific composite adhesives can maintain strong bonding and meet all regulatory requirements, even at high temperatures . Bagging is being applied to objects that are more erosive, such as oily foods, iodine-containing foods, and special packaging such as swimming pool chemicals. This requires constantly adjusting the formulation of the adhesive and conducting prescribed tests to ensure that its product can effectively resist the eroding property of the packaged product, so that the package is entirely reliable and does not leak.
Advanced adhesive technology helps customers complete film compounding, bag building and filling operations with greater speed and reliability. The combination of barrier-free solvent-free adhesives can reduce or eliminate the need for metallized films, foils, barrier coatings, or co-extruded structures, allowing customers to save a great deal of time and money.
