Food is food to safety first. With the continuous development of the packaging industry, people pay more and more attention to the safety and convenience of packaging. So what factors will affect the safety of food packaging? Packaging materials are naturally a very important reason, followed by packaging methods. Therefore, in today's rising health awareness, safe and effective health care has attracted considerable attention, which has directly promoted the development of bag-in-box packaging. The bag in the box, as its name suggests, consists of a soft, different material, a bag with a fluid outlet and a corrugated box outside. The inner bag of the bag is made of composite film and uses different materials to meet the needs of different liquid packaging. It can provide 2-10 liters aluminum foil bag, transparent bag, single or roll standard products, with standard canned mouth. Marking logo can also be customized.
Compared to traditional packaging forms, bag-in-box packaging has a very clear competitive advantage, such as longer shelf life, better light and oxygen barrier properties, very little material usage, and recycling, can be used in the same irrigation The equipment can handle a wide range of product specifications and can be used for aseptic/non-sterile/cold filling/hot filling/multiple treatment processes, from semi-automatic to fully automatic filling equipment for flexible selection, improved storage and transportation Efficiency, reduced storage and transportation costs, significantly reduced packaging costs, etc. At present, the bag-in-box packaging forms are widely used in fruit juices, wines, fruit drinks, mineral waters, edible oils, food additives, industrial pharmaceuticals, medical reagents, liquid fertilizers, and pesticides.
According to market research, the bag in the box has obvious environmental benefits. As a more low-carbon and environmentally-friendly packaging form, the bag-in-box greatly reduces the use of packaging materials and energy consumption, and reduces the adverse effects of packaging on the environment. The bag in the box uses less packaging material, which is only 1/5 of the rigid container. The used bag-in-box packaging is very easy to separate and recycle, and can be completely recycled. The bag in the box can be completely folded and stored before and after use, which greatly reduces packaging storage and transportation costs and reduces energy consumption. Most of the bags in the box are disposable, avoiding the influence of chemical disinfection and cleaning on the environment and damage. The maximum packaging capacity is up to 1,400 liters, which means that the unit capacity of the product has less packaging cost and longer product storage period. Reduced waste due to product deterioration.
Smurfit Kappa recently stated that at present, the demand for box-in-box packaging for companies providing dairy products for the food service industry is gradually increasing. The retail industry has the greatest room for growth.
Veronika Necasova of Smurfit Kappa said: “The dairy industry is in high demand for bag-in-box packaging, especially fast food restaurants selling smoothies and milkshakes. They are already accustomed to using box-in-box packaging.”
She said: "We believe that the growth of bag-in-box packaging in the smoothies and milkshakes industry is the fastest, and the growth of the entire dairy industry is also in a healthy state. Only the retail dairy industry uses less bag-in-box packaging." At the same time, portable product manufacturers are more inclined to seek soft packaging. Manufacturers of dairy smoothies and yogurt drinks are more inclined to use bag packaging instead of plastic packaging."
Necasova believes that the reason why dairy companies have increased demand for bag-in-box packaging is because this packaging model can improve product quality. She said: “The reason that people in the industry like the box-in-box packaging model is that it meets the strict requirements of the health standards regulations because the packaging is one-off.”
In general, the reason why the beverage industry uses the bag in the box is based on its health, long shelf life, and no harm to the environment. And people are increasingly discovering that there are many advantages to using a bag in a box: long shelf life, convenience, environmental friendliness, suitability for asepsis and high temperature, clean filling techniques, and the like.
At present, the wine industry is still the largest market for bag-in-box, but fruit juices, liquid eggs, water, olive oil and other edible oils are also increasingly used in box-in-box packaging.
At the same time, the market development status of the vertical packaging bags is also very good. Wine and cocktails are the main factors that contribute to this development. A series of vertical bags produced by Smurfit Kappa witnessed this development first. Demand for such packaging is particularly strong in the cocktail markets in the United States, Britain, France, and Northern Europe.
With the implementation of global environmental protection legislation and the country’s environmental protection policy requirements, especially the enhancement of people’s environmental awareness, the bag in the box is very attractive. The low carbon and environmentally friendly packaging will be applied in more fields.
