Soft bag and hard bag are a kind of packaging material, which refers to the physical properties of the package. Soft bag refers to the packaging material is soft and flexible, and its shape can be deformed under the action of external force; The hard bag refers to the packaging material is more rigid, not easy to deform the packaging material. The most fundamental difference between soft bags and hard bags is the nature of the material.

Differences
1. Different materials

Soft bags are generally made of plastic film materials, such as polyethylene (PE), polypropylene (PP), nylon (PA), polyester (PET), etc. Hard bags are generally made of hard materials such as iron, aluminum and organic hollow plates.

2. Different usage scenarios

Soft bag is suitable for products that need to withstand pressure, tear, flexibility, high transparency, light weight and so on. For example: food packaging, pharmaceutical packaging, daily necessities packaging, etc.; The hard bag is suitable for goods that need to withstand pressure, earthquake, beautiful appearance, and are not easy to deform. For example: beverage cans, cosmetic bottles, medicine boxes, etc.

3. Different production costs

Because the soft bag is made of soft materials such as plastic film, the production cost is relatively low, while the hard bag needs to use more expensive materials and processing technology, and the relative production cost is higher.

Applicable scenarios
Both soft and hard packages have their own application scenarios, and you need to choose different packaging methods according to different situations. When choosing the packaging method, it is necessary to consider the nature of the product, the form of packaging, market demand and other factors to develop the most appropriate packaging program.

In general, soft packages and hard packages each have their own characteristics and application scenarios, need to be selected according to the actual situation. Soft package is suitable for the need for flexibility, high transparency, low cost and so on; The hard bag is suitable for the need for beautiful appearance, good pressure resistance, suitable for high-end products. Both have a wide range of use scenarios in market applications, and also promote the continuous development of the packaging industry.
