With its changeable style and excellent shelf image, special-shaped bags form a unique attraction in the market, and become an important means for enterprises to expand their popularity and increase their market share. Special-shaped bags have various shapes and shapes, so in the design process, some points need to be paid attention to.1. The advantages of special-shaped bagsSpecial-shaped bag is a kind of irregular packaging bag, which is divided into middle seal, four-side seal, three-side seal, etc. It breaks people’s impression that the packaging bag is square and square. It is novel, easy to identify, and can more intuitively highlight product features, such as Fruit slices designed in corresponding shapes allow people to understand product information at a glance. Compared with traditional bottled packaging, it is more energy-efficient and environmentally friendly, and can save storage costs and transportation costs. These advantages of special-shaped bags make them widely used in food, daily chemical, toys, medicine, electronics and other fields.2. Design Notes 1, Capacity changes. Everyone is familiar with the specifications and capacity of the traditional shape of the packaging bag. However, when the shape of the packaging bag is changed, the capacity will inevitably change. Therefore, it is necessary to recalculate the capacity according to the size of the packaging bag during the design process. 2, Soft edges. Due to the irregularity of the special-shaped bag, there will be sharp edges and corners. It is easy to puncture other packaging or hurt the user during storage and use. Therefore, the edges of the special-shaped bag should be as soft as possible and avoid sharp corners. 3Pay attention to sealing. Ordinary packaging bags are relatively simple to seal because they are horizontal and vertical. However, special-shaped bags have a sense of line. When heat-sealing, it is necessary to carefully set heat-sealing related parameters according to the opening direction, line shape, and sealing position of the special-shaped bag.3. Shaped bag type 1, Shaped bag nozzle bag. Generally, a suction nozzle is added to the special-shaped bag, mainly to facilitate the dumping of the internal items, and it can be re-sealed after use, which is convenient for multiple use. Special-shaped bag nozzle bag is mainly used in liquid packaging, such as beverages, jelly, tomato sauce, salad dressing, shower gel, shampoo, etc. 2, Shaped bag zipper bag. The special-shaped zipper bag is a zipper added to the lower part of the bag opening, which is convenient for multiple unsealing. Zipper bags are also convenient for food preservation and multiple uses, but they are not suitable for liquids, and are more suitable for dry items with lighter weight, such as chocolate, biscuits, tea, dried fruits, candies, etc. 3Shaped bag imitation mouth bag. The imitation mouth bag means that the bag does not have a suction nozzle, but in the design process, the opening part of the bag is designed to resemble a mouth shape. The purpose of this kind of bag is basically the same as that of special-shaped bag nozzle bag, and it is also mainly used for liquid packaging, but because it cannot be sealed once it is opened, it is mostly used for liquid refill bags or bags with smaller specifications.
