Product Overview

The Haitel HTL-D420 Screw-feeding Powder Automatic Packing Machine is a vertical-form-fill-seal (VFFS) solution engineered for accurate, high-speed dosing and bagging of powders and fine granules. Built around a servo-driven film drawing-down system and an integrated screw feeder, the HTL-D420 completes the entire packaging cycle — feeding, measuring, filling, sealing, date printing, gas flushing (or exhausting), counting, and finished-product delivery — in a single continuous operation when paired with the appropriate feeding and metering equipment.

With a rated speed of around 30–60 bags per minute and a generous filling range of 50–1000 g, the machine is a dependable workhorse for food, seasoning, and related powder producers who need consistent portion control without sacrificing throughput. Its advanced, rational construction makes day-to-day adjustment, operation, and maintenance genuinely straightforward (see product catalog, corresponding section).

Why Choose It

• Servo-controlled film drawing-down system — delivers precise, repeatable bag length and clean film transport for a professional finished pack every cycle.
• Automatic film rectifying (deviation correction) function — keeps the film perfectly aligned, eliminating skew and reducing material waste.
• Intelligent alarm system — built-in fault alerts minimize scrap and downtime by catching issues early, before they turn into wasted batches.
• Fully integrated packaging process — when equipped with feeding and measuring units, it automatically handles feeding, measuring, filling, sealing, date printing, charging/exhausting, counting, and product outfeed.
• Flexible bag formats — produces pillow-type bags, standing (gusseted) bags, and punched/hang-hole bags, or can be configured to custom bag styles on request.
• Wide material compatibility — ideal for a broad range of powders and granules such as sugar, salt, coffee, and similar products, giving you room to grow your SKU mix.

Typical Application Scenarios

• Seasoning & condiment plants — packaging table salt, sugar, spice blends, and powdered soup bases in consumer or food-service sizes.
• Coffee & beverage processors — dosing ground coffee, instant coffee, and malted drink powders into retail pillow or stand-up pouches.
• Food ingredient manufacturers — bagging flour mixes, baking powder, starch, and other fine powders with tight weight accuracy.
• Contract packing operations — running multiple powder SKUs where quick changeover and format flexibility protect margins.
• Pharmaceutical & nutraceutical auxiliaries — non-regulated powder dosing where clean, sealed, dated packs are required (confirm material suitability with Haitel sales for confirmation).

Customer FAQs

1. What kinds of products can the HTL-D420 package? It is designed for powders and fine granules such as sugar, salt, and coffee, as well as similar free-flowing or semi-free-flowing materials. For sticky or highly cohesive powders, contact Haitel sales for confirmation on auger and screw configuration.

2. How fast can it run? Typical output is about 30–60 bags per minute. Actual speed depends on the wrapping film and the characteristics of your material, so it is best confirmed against your specific product.

3. What bag styles are supported? The machine makes pillow-type bags, standing (gusseted) bags, and punched/hang-hole bags, and can be adapted to customer-required bag formats.

4. What is the dosing accuracy? Accuracy is ≤ 1.5%, which suits most retail and food-service powder packaging needs.

5. What film materials can I use? It works with thermal composite films such as BOPP/CPP and PET/AL/PE, within a thickness of 0.04–0.09 mm and a maximum film width of 420 mm.

6. What utilities does the machine need? It requires 380 V / 50 Hz (four-wire, three-phase) power, 5 KW total power, and a compressed air supply of 0.8 MPa at 0.4 m³/min with an air compressor of at least 1 CBM.

7. Is it difficult to operate and maintain? No. The machine features an advanced, rational design with servo film control and automatic deviation correction, making adjustment, operation, and maintenance convenient.

8. Can it print production dates on the pack? Yes. When equipped with the relevant accessory, it performs date printing, gas charging/exhausting, counting, and finished-product delivery automatically.
