The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.
Additionally, the sturdiness of large paper bags makes them a practical choice for carrying heavier items. Unlike smaller paper bags, which may not provide sufficient support, large paper bags can safely hold bulkier goods, making them ideal for grocery stores and retail outlets.

They are typically made from multi-layer materials that secure the freshness of the tea by preventing exposure to air, moisture, and light. This preservation is essential for maintaining the tea's flavor and aroma, ensuring that consumers enjoy the full experience of their beverage.
From a functionality standpoint, stand-up pouches are incredibly versatile. They are available in various sizes, colors, and materials, allowing brands to customize them according to their specific requirements. Such flexibility makes them suitable for a wide range of products—from dry goods to liquids, and even fragile items. Manufacturers can choose from a variety of materials, including plastic, foil, or biodegradable options, to create pouches that provide the necessary protection for their food products while also appealing to environmentally conscious consumers.
