How does the durability of transparent bag-in-box materials for liquid eggs and the effect of long-term storage on the quality of liquid eggs?

The durability of transparent bag-in-box materials depends mainly on the specific materials used. For example, polyvinyl chloride (PVC) sheets have strong mechanical properties, are lightweight, transparent, low-cost, impact-resistant and shock-proof, and are therefore ideal materials for automated poultry egg packaging. For transparent bag-in-box packaging of liquid eggs, durability means that the material can withstand various physical stresses such as squeezing, vibration and friction during transportation, storage and use without being easily damaged or deformed. Such durability ensures that the liquid eggs remain intact and safe in the packaging.
The effect of long-term storage on the quality of liquid eggs
The effect of long-term storage on the quality of liquid eggs is multifaceted. Microorganisms in liquid eggs, such as streptococci, enterococci and bacilli, may gradually grow during storage and cause the liquid eggs to spoil. Even after pasteurization, some psychrophilic bacteria and bacilli may survive and multiply under refrigerated conditions.
The protein in liquid eggs may change during storage due to oxidation, enzymatic reactions or microbial metabolism, resulting in a decline in quality. These changes may include color changes, odors, and reduced nutritional value.
The choice of packaging materials can also affect the long-term storage quality of egg liquid. For example, if the packaging material is not breathable or has poor sealing, it may lead to poor exchange of moisture and gas in the egg liquid, further accelerating the spoilage of the egg liquid.
The durability of the transparent bag-in-box material is crucial to the safety of the egg liquid during storage and transportation, while long-term storage may lead to a decline in the quality of the egg liquid. Therefore, when selecting packaging materials and storage conditions, various factors need to be considered comprehensively to ensure that the egg liquid maintains the best quality during storage.

How does the transparent bag-in-box design ensure convenience and stability during carrying and storage?

Material selection:
The transparent bag-in-box bag is usually made of several layers of metallized film or other plastics, which not only ensures the transparency of the bag, but also provides a certain strength and stability.
When selecting these materials, it is necessary to consider their tear resistance, temperature resistance, and chemical corrosion resistance to ensure that they will not be damaged or leaked during carrying and storage.
Structural design: The bag is placed inside a corrugated fiberboard box, which provides additional protection and stability to prevent the bag from being squeezed or deformed during carrying. The design of corrugated fiberboard boxes usually takes into account load-bearing and stacking convenience, so that multiple boxes can be easily stacked and transported. Ease of operation: The bag is usually equipped with a tap for easy removal of liquid. This design makes it easier to use without opening the entire box. The bag can be used as a single bag or roll bag for semi-automatic machines, where there are perforations between the bags to facilitate the operation of the automatic filling system. Temperature adaptability: The transparent bag in box can be used in a wide temperature range, such as refrigerated product temperatures up to 85°C (185°F). This temperature adaptability ensures stability under different storage conditions. Integrity and anti-counterfeiting: The design of the transparent bag in box needs to maintain the stability and integrity of the material to prevent leakage or damage during carrying and storage. At the same time, in order to ensure the authenticity of the product and prevent counterfeiting, anti-counterfeiting measures such as special printing processes or labels need to be considered in the design.
