Does a Six-Line Bag Machine Multiply Your Output?

You're running a bag production line, and the order volume keeps climbing. A single-line machine requires more operators, more floor space, and more time to meet the demand. A Bottom Seal Bag Making Machine with six parallel lines changes the output equation entirely. The CX-TB-320*6 produces six bags per cycle across six independent lanes, delivering a combined speed of 600 pieces per minute. This article explains how the double-layer six-line architecture works, what the hot sealing and cold cutting process delivers for T-shirt bag quality, and what to verify before specifying a multi-line system for your production floor.

What Does Six-Line Output Mean for Your Production?

The CX-TB-320*6 operates six parallel lanes, each producing its own bag. At a speed of **100*6 pcs/min**, the machine delivers a combined output of 600 bags per minute. This is the core advantage of the multi-line design: instead of running one bag at a time, the machine runs six. The bag making width is 320mm, and the produce length ranges from 250mm to 600mm. Film thickness compatibility is 0.01-0.04mm, covering the thin-gauge films used in T-shirt bags, shopping bags, and lightweight packaging. The total power is 10KW, and the machine dimensions are 7.5×1.8×2m with a weight of 2.5T.

Combined Output and Lane Configuration

Six lanes running at 100 pieces per minute each produce 600 bags per minute. That's 36,000 bags per hour during continuous operation. For converters supplying retail chains, grocery stores, or e-commerce fulfillment centers, this output level supports high-volume contracts without requiring multiple machines.

Bag Size Range for T-Shirt and Shopping Bags

The 250-600mm produce length and 320mm bag width cover the standard T-shirt bag formats used in retail and grocery. The 0.01-0.04mm film thickness accommodates the HDPE and LDPE films commonly used for these applications.

How Do Hot Sealing and Cold Cutting Work Together?

The CX-TB-320*6 uses hot sealing to bond the bag layers and cold cutting to separate the finished bags. Hot sealing applies controlled heat and pressure to fuse the film layers, creating a seal that holds under load. Cold cutting then shears the sealed film cleanly, producing a sharp edge without the melted bead that hot cutting can leave. This combination is particularly important for T-shirt bags, where the handle cutout and the bag edges must be clean and uniform. The double-layer configuration means the machine processes two layers of film simultaneously, doubling the material throughput without doubling the machine footprint.

The Hot Sealing Process for Strong Bonds

Hot sealing uses a heated bar or blade to melt the film layers together. The temperature and pressure are controlled to ensure a consistent seal across the full bag width. For T-shirt bags, the seal must hold the weight of the contents without separating at the handle or the bottom.

Cold Cutting for Clean Edges

Cold cutting uses a sharp blade to shear the film after sealing. Unlike hot cutting, which melts through the film and can leave a rough, beaded edge, cold cutting produces a clean, straight cut. The result is a bag that looks professional and handles well in downstream operations.

Technical Specifications for Production Planning

Power and Footprint for Facility Planning

The 10KW total power and 7.5×1.8×2m dimensions allow facility planners to prepare the electrical supply and floor space before installation. The 2.5T weight requires a stable floor and adequate clearance for material loading and finished product removal.

Film Compatibility and Thickness Range

The 0.01-0.04mm film thickness range covers the thin-gauge films used in T-shirt bags and lightweight shopping bags. The double-layer configuration processes two film layers simultaneously, which is essential for bags that require reinforced handles or dual-layer construction.

Where Does a Six-Line Machine Deliver the Most Value?

The CX-TB-320*6 serves production environments where high-volume T-shirt bag output is required. Retail packaging suppliers, grocery bag manufacturers, and contract bag producers all benefit from the combination of six-line output and compact footprint.

• Retail and grocery bags — high-volume T-shirt bags for supermarkets and convenience stores

• E-commerce packaging — lightweight mailer and shopping bags for online fulfillment

• Promotional and event bags — branded bags for campaigns and trade shows

• Industrial and household bags — utility bags for hardware, produce, and general use

Retail and Grocery Applications

Supermarkets and grocery chains consume T-shirt bags at enormous volume. The CX-TB-320*6 produces 600 bags per minute, providing the throughput needed to supply multiple store locations from a single production line.

E-Commerce and Promotional Bags

E-commerce fulfillment centers and promotional campaigns require large quantities of lightweight bags. The six-line output and 0.01-0.04mm film range cover these applications.
