[0002] Currently, there is an endless stream of nutritional supplements for breastfeeding products on the market. These supplements primarily come in solid, powdered, and liquid forms, and different packaging bags are available for these different nutritional supplements. Consequently, there are also a wide variety of direct packaging options for nutritional supplements. Liquid nutritional supplements are typically packaged in bags, but these packaging options still have some drawbacks. Currently, hand-tearable beverage packaging bags typically feature a straight indentation in the upper left or right corner to guide the user through the bag, insert a straw, and drink. However, due to the presence of a drink inside the bag after the straight indentation, and the stickiness of some beverages, the bag often remains closed. This can be achieved by gently squeezing the bag, allowing the internal air to pass through the bag opening and allowing the straw to be inserted. However, the force must be appropriate to prevent the drink from spraying out, which is why manufacturers use easy-tear packaging bags.
