Background: A food plant's packaging workshop (typical scenario) seals hundreds of plastic bags every day — candies, dried goods, powdered foods. Previously, workers used manual heat sealers: pressing each bag mouth by hand, judging temperature by feel. Output was slow, seals were uneven, and sealing became the bottleneck whenever orders peaked.
The Challenge:
▪ Low output: manual sealing reaches only about a dozen bags per minute per worker;
▪ Inconsistent seals: temperature varies by hand-feel — overheated film tears, underheated seals leak, causing rework;
▪ No continuous operation: manual sealers work intermittently and cannot keep pace with a packaging line;
▪ High product loss: weak seals let in moisture and dust, leading to spoilage and breakage in storage and transport;
▪ Labor cost: sealing needs dedicated staff.
The Solution: The workshop installed a vertical/horizontal continuous film sealing machine (specifications per product datasheet):
| Specification | Value |
|---|---|
| Power supply | AC220V / 50Hz (110V available on request) |
| Power | 620W |
| Sealing speed | 3-12 m/min (stepless speed control) |
| Sealing width | 6-10mm |
| Film thickness | 0.02-0.80mm |
| Temperature range | 0-300°C (electronic thermostatic control) |
| Conveyor load | ≤5kg |
| Machine size | 820×400×580mm |
| Gross weight | 25kg |
How It Works: Bags are filled and their mouths fed into the sealing unit; the electronically controlled heating block seals the film at a precise 0-300°C while the conveyor (with adjustable height) carries bags continuously at 3-12 m/min. A cooling block with forced-air cooling firms up the seal for uniform, durable closure. Thickened conveyor belts prevent misalignment and breakage; reinforced rollers and efficient heat-dissipation slots support long continuous runs.
Results:
▪ Speed & continuity: continuous 3-12 m/min sealing integrates directly with packaging lines — no more peak-season overtime;
▪ Seal quality: electronic thermostatic control gives uniform, airtight seals every time;
▪ Versatility: seals plastic bags of various film types (0.02-0.80mm), with no limit on sealing length;
▪ Durability: simple electric control and precision drive keep failure rates extremely low for long service life;
▪ Low loss: sealed packages are dust-proof, moisture-proof and damage-resistant, cutting product loss in storage and transport;
▪ Easy deployment: compact size (820×400×580mm), only 25kg, 620W low power, 220V plug-and-play (110V available).
Best Fit: Food, pharmaceutical, chemical, agricultural and grain industries — candies, dried goods, snacks, powders and similar bagged products; pairs with packaging lines in factories and stores.
