The Evolution of Hot Tea Packaging Pouches

2. Cost-Effectiveness Poly pouches are generally less expensive to produce compared to rigid packaging options like glass or metal containers. Their lightweight nature also leads to reduced shipping costs, making them a cost-effective choice for businesses.

A4 resealable plastic bags are designed to fit documents and items that are A4-sized (approximately 21 x 29.7 cm or 8.3 x 11.7 inches). Made of high-quality polyethylene or similar materials, these bags come with a ziplock or adhesive seal that allows for easy opening and closing, thus ensuring that the contents are protected from dust, moisture, and wear. Their transparent nature offers a clear view of the contents, which aids in quick identification and enhances organization.

A vertical sealer is a packaging machine designed to seal products in a vertical position. Unlike horizontal sealers, which operate with products placed flat, vertical sealers are commonly used for liquid or powder products that might flow or spill if not contained upright. These machines employ heat sealing, ultrasonic sealing, or impulse sealing technologies to create airtight seals, which are crucial for maintaining product integrity.

While aluminum foil Faraday bags provide essential protection, they have limitations. They are most effective against certain frequencies, particularly low-frequency fields. High-frequency signals may not be entirely blocked. Additionally, their construction can be prone to wear and damage, which can affect their shielding capabilities.
