This is how the special-shaped bag is designed to win at the starting line. With its changeable style and excellent shelf image, the special-shaped bag has formed a unique attraction in the market, and has become an important means for enterprises to open up popularity and increase market share. The special-shaped bag has various shapes, and some key points should be paid attention to in the design process.

Advantages of 1. special-shaped bags

Special-shaped bag is an irregular packaging bag, which is divided into middle seal, four-sided seal, three-sided seal, etc. It breaks people's impression of square, novel and easy to identify packaging bags, and highlights product features more intuitively. For example, fruit slices are designed into corresponding shapes, so that people can know product information at a glance. Compared with traditional bottled packaging, it is more energy-saving and environmentally friendly, and can save storage and transportation costs, these advantages of special-shaped bags make them widely used in food, daily chemicals, toys, medicine, electronics and other fields.

2. Design Considerations

1. Capacity changes, the specifications and capacity of traditional packaging bags have basically formed a fixed pattern, which is familiar to everyone, but after the shape of the packaging bag is changed, the capacity will inevitably change, so the design process needs to be recalculated according to the size of the packaging bag Capacity.

2. Soft edges, due to its irregularities, special-shaped bags will encounter sharp edges and corners, which can easily stab other packaging or hurt users during storage and use. Therefore, the edges of the special-shaped bag should be as soft as possible and avoid sharp corners.

3. Pay attention to sealing. Ordinary packaging bags are relatively simple to seal because they are horizontal and vertical, but special-shaped bags have a sense of lines. When heat sealing, heat sealing should be carefully set according to the opening direction, line shape and sealing position of the special-shaped bag. Related parameters.

Three. Types of special-shaped bags

1. Special-shaped bag suction nozzle bag: Special-shaped bag will generally add a suction nozzle, mainly for the convenience of dumping the internal items, which can be reopened after use, which is convenient for multiple use. The special-shaped suction nozzle bag is mainly used for liquid packaging, such as beverages, jelly, ketchup, salad dressing, shower gel, shampoo, etc.

2. Special-shaped zipper bag: Special-shaped zipper bag is a zipper added at the lower part of the bag mouth, which is convenient to open multiple times. The zipper bag is also convenient for food preservation and reuse, but it is not suitable for liquids, and is more suitable for light-weight dry goods, such as chocolate, Biscuits, tea, dried fruit, candy, etc.

3. Special-shaped bag imitation pocket bag: imitation mouth bag means that the bag has no suction nozzle, but in the design process, the opening part of the bag is designed to be similar to the mouth. The purpose of this bag is basically the same as that of special-shaped bag suction nozzle bag, and is mainly used for liquid packaging. However, it cannot be sealed after opening, so it is mostly used for liquid filling bags or bags with smaller specifications.
