2.Module Details Comparison

2.1 PMTD-SF01 Tearing Tape and Sealing Module

—— Exclusive for Self-Adhesive Bags · No Residue · Efficient & Eco-Friendly

Core Advantages

Intelligent Adhesive Tearing Technology: Automatically identifies the adhesive strip position, accurately grasps and tears it (error ≤ 2mm). Waste is collected automatically, avoiding incomplete tearing or residue from manual operation.

Instant Tear & Seal: No additional consumables required, relying on the bag's built-in self-adhesive strip. Sealing flatness rate ≥ 99%.

Flexible Adaptability: Compatible with envelope-style adhesive bags of 20-42cm width and 28-52cm length. Seamlessly connects with folding machines and bagging machines.

Technical Parameter

2.2 PMTD-TJ01 Transparent Tape Sealing Module

—— Flexible Multi-Strip Adhesion · Adjustable Sealing Strength · Universal First Choice

Core Advantages

High Adhesion Flexibility: Supports 1-3 strips of transparent tape for sealing. Spacing and position are adjustable to meet different bag mouth strength requirements.

Low-Cost Roll Consumables: Uses universal 1-1.8cm wide transparent tape rolls. A single roll can seal over 3,000 pieces, reducing consumable costs by 50% compared to manual operation.

Precise Position Calibration: Automatically calculates the bag mouth position with a minimum/maximum taping error ≤ 3mm.

Technical Parameters

2.3 PMTD-RF01 Automatic Heat Fusion Sealing Module

—— Essential for High-End Packaging · Seamless Sealing · Moisture & Dust Proof

Core Advantages

Dual-Mode Sealing:

Heat Sealing & Hot Cutting: No edge residue, ideal for size-sensitive scenarios (saves 5% bag material).

Heat Sealing & Cold Cutting: 1cm edge left, suitable for retail packaging that requires repeated opening.

Automatic Waste Trimming: Precisely cuts excess bag material before sealing (error ≤ 1mm), eliminating manual trimming.

High-Temperature Stability Technology: Constant temperature control at 120-220℃, suitable for bags of different thicknesses (0.03-0.1mm).

Technical Parameters

2.4 PMTD-YK01 Automatic Snap-fastenner Bag Sealing Module

—— Press-Lock Exclusive · Adjustable Engagement Force · Reusable Bag Friendly

Core Advantages

Precise Press-Lock Alignment: Automatically identifies the sealing edge of press-lock bags, aligns with the lock position accurately (error ≤ 2mm), and completes engagement via mechanical structure.

Wide Compatibility: Adapts to various press-lock bag specifications, with lock width ranging from 0.8-2cm, supporting both single-row and double-row lock designs.

Adjustable Sealing Tightness: Optional single/double-channel sealing modes; the press-lock engagement force is adjustable to ensure tight, non-loosening closures.

Technical Parameters

Core Functions

Automatic Incoming Material Detection: Avoids empty bag sealing by sensing the arrival of bags.

Integrated Automatic Process: Can be combined with LC AUTO press-lock bag automatic bagging machine to form a fully automated "bagging → press-lock sealing" workflow.
