Designing a fruit and vegetable blister box to optimize the preservation effect is a comprehensive consideration process involving material selection, structural design, function realization and other aspects.
First of all, choosing the right material is the basis for designing a fresh-keeping fruit and vegetable blister box. High-quality materials should have good barrier properties, air permeability and weather resistance. Barrier properties can prevent the invasion of external oxygen, moisture and microorganisms, and extend the shelf life of fruits and vegetables; air permeability helps fruits and vegetables breathe in the package to maintain freshness; weather resistance ensures that the fruit and vegetable blister box can maintain stable performance under different climatic conditions. Common materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. The specific selection should be determined according to the type of fruits and vegetables, storage time and environmental conditions.
In terms of structural design, attention should be paid to the sealing and stability of the fruit and vegetable blister box. Sealing can be achieved through technologies such as heat sealing and ultrasonic edge sealing to effectively prevent the entry of air and microorganisms. Stability requires that the fruit and vegetable blister box is not easily deformed or damaged during stacking and transportation to protect fruits and vegetables from mechanical damage. In addition, the corners of the fruit and vegetable blister box should be designed to be rounded without sharp angles to reduce friction and squeezing of fruits and vegetables.
The design of air holes is crucial for the preservation of fruits and vegetables. Reasonable air hole layout and aperture size can achieve gas exchange in the fruit and vegetable packaging, maintain appropriate oxygen and carbon dioxide concentrations, and thus delay the aging and deterioration of fruits and vegetables. The design of air holes should be adjusted according to the respiration intensity and storage conditions of fruits and vegetables to achieve the best preservation effect.
Moisture-proof and mildew-proof are important parts of fruit and vegetable preservation. Moisture-proof agents or desiccants should be used in the fruit and vegetable blister box to absorb excess moisture in the package and prevent fruits and vegetables from getting damp and moldy. At the same time, the material of the fruit and vegetable blister box should also have good moisture-proof properties to prevent external moisture from invading.
Different fruits and vegetables have different preservation needs and characteristics. Therefore, when designing a fruit and vegetable blister box, factors such as the shape, size, texture and shelf life of fruits and vegetables should be fully considered. For example, for perishable fruits and vegetables, a tighter sealing structure should be designed; for fruits and vegetables that need ventilation, the number and diameter of air holes should be increased.
The design of fruit and vegetable blister box should also take into account the convenience of consumers. For example, the opening method of fruit and vegetable blister box should be simple and easy, so that consumers can quickly open and take out fruits and vegetables. At the same time, the transparency of fruit and vegetable blister box is also very important, so that consumers can intuitively see the freshness and quality of fruits and vegetables.
Environmental protection and sustainability are also factors that cannot be ignored when designing fruit and vegetable blister box. Degradable or recyclable materials should be given priority to reduce pollution to the environment. At the same time, the design of fruit and vegetable blister box should also be easy to recycle and reuse to reduce production costs and resource waste.
Designing fruit and vegetable blister box to optimize the preservation effect requires comprehensive consideration of multiple aspects such as material selection, structural design, air hole design, moisture and mildew resistance, adaptation to different characteristics of fruits and vegetables, convenience for consumers to use, and attention to environmental protection and sustainability. Through scientific and reasonable design, the shelf life of fruits and vegetables can be extended and consumers' purchasing experience and satisfaction can be improved.
