What Inner and Outer Bag Packing Means and When You Need It

Inner and Outer Bag Packing Explained

The C18 Automatic filter paper tea bag outer envelope machine forms and fills both inner and outer bags simultaneously from a single roll of material. It is designed for small granular products such as tea leaves, medicinal tea, and health care tea. The inner bag is made of filter paper with a thread and tag attached, while the outer bag is made of composite paper. The machine uses a new heat sealing type to seal both bags at once, reducing manual handling and improving efficiency. Photoelectric positioning ensures accurate tag attachment and outer bag formation.

When You Need Inner and Outer Bag Packing

Use this machine when you need to package tea or similar products in a double-layered format for retail, branding, or protection. The inner filter paper bag holds the product and allows steeping, while the outer composite paper bag provides a clean, branded surface for labeling and shelf appeal. This setup is ideal for tea blenders, health tea producers, and contract packers who require a professional, ready-to-sell package without manual assembly.

How It Works

The machine unwinds the filter paper roll for the inner bag and the composite paper roll for the outer bag. Both are formed, filled, sealed, and cut in one continuous process. The tag is attached using photoelectric positioning to ensure correct alignment. The finished double bag is discharged ready for packing into boxes or display trays. The entire process runs automatically with minimal operator intervention.
