Self-standing feature: The bottom is treated with a special process, allowing it to stand independently on a flat surface such as a desktop. This makes the products more conspicuous when displayed, like on supermarket shelves, they can be neatly upright displayed to attract consumers' attention; When stored at home, even if some hawthorn cakes are taken out, the rest can be placed steadily, making it convenient to take and enhancing the convenience of use.
Overall shape: It is in the form of a rectangular bag, with a certain three-dimensional space. It can hold 660g of hawthorn cakes. The bag body is regular, and the printed patterns and text are distributed in an orderly manner, which is convenient for information transmission and brand display.
Exploration of Material Structure
Judging from the appearance and the conventional design of food packaging, it is highly likely to be made of composite materials, with clear division of labor among each layer:
Outer layer: Mostly made of polyester (PET) material. It has excellent printability, allowing pink, purple and other patterns to be bright and clear in color. The "Yida" brand logo, hawthorn cake product information and other prints are firm and not easy to fade. At the same time, it endows the packaging bag with a crisp texture, is resistant to stretching and wear, protects the products inside the bag, and reduces the risk of damage during transportation and handling.
Middle layer: May be made of nylon (PA) material. Nylon has excellent flexibility and puncture resistance. Hawthorn cakes are in block form. During the packaging process or handling, internal squeezing and friction may occur. The nylon layer can resist punctures from sharp objects, prevent the packaging bag from being damaged and leaked, and maintain its sealing property.
Inner layer: Commonly used is polyethylene (PE). PE is non-toxic and has excellent heat-sealing properties. It can tightly seal, block air and moisture, delay the oxidation and moisture absorption of hawthorn cakes, and extend their shelf life. Its softness is also suitable for food contact, ensuring food safety.
Potential barrier layer: If stronger preservation is required, an aluminum foil (AL) layer may be included. Aluminum foil can effectively block oxygen, light and odors. For instance, hawthorn cakes are easily affected by light in terms of flavor and quality. The aluminum foil layer can block light, maintain the original taste and color of the product, and enhance the preservation effect.
Overall, this packaging bag optimizes the display and usage experience through a reasonable bag shape design, and builds a protective system with multi-layer composite materials. It works in synergy in protecting the product, conveying information, and extending the shelf life, facilitating the storage, sales, and consumption processes of Yida Hawthorn cakes.
