DGX L-Bar Sealer | Automatic Shrink Wrapping & Packaging Machine FAQ
What is an L-Bar Sealer, and how does it work?

An L-Bar Sealer is an automated machine that forms an “L”-shaped seal around a product. The DGX sealer uses a film roll and an L-shaped sealing bar. The product moves into the machine on a conveyor, the film is draped over it, and the hot bar descends to seal and cut the film simultaneously, creating a tight, professional package.

What types of products and industries is this machine suitable for?

The DGX L-Bar Sealer is highly versatile. It is ideal for:

Industries: Food & Beverage, Pharmaceuticals, Cosmetics, Electronics, Stationery, and Consumer Goods.

Products: Boxes, books, CDs/DVDs, multi-packs (bundling), bottles, and any uniformly shaped items that require a secure, shrink-wrapped package.

What film materials can the DGX L-Bar Sealer use?

It is compatible with most common shrink films, including Polyolefin(POF), Polypropylene‌(PP), Polyvinyl chloride‌(PVC), Polyethylene(PE). For specific films or anti-static varieties, please consult with our technical team for potential machine configuration adjustments.

How quickly can it package items? What is the production speed?

The machine can achieve speeds of up to 30 packages per minute. The actual throughput depends on product size and operator speed, but it is designed for medium to high-volume production lines.

Is it difficult to change the machine settings for different product sizes?

Not at all. The DGX L-Bar Sealer is designed for quick changeover. Key parameters like sealing time and temperature can be easily adjusted via the user-friendly digital control panel. The sealing height can often be mechanically adjusted to accommodate different product heights.

What‘s the difference between a manual, semi-automatic, and automatic L-Bar Sealer?

Manual: Requires manual product and film placement.

Semi-Automatic: Operator places the product; sealing and cutting are automatic.

Automatic: Fully automated feeding, sealing, and discharge—ideal for high-volume production lines.

Can the DGX L-Bar Sealer be connected to a shrink tunnel?

Yes. It’s designed to work seamlessly with DGX shrink tunnels (RS series) for full packaging automation — from sealing to heat shrinking.

What are the main advantages of the DGX model over competitors?

Our key advantages include:

  • Robust Construction: Industrial-grade components for long-term durability.
  • Precision Control: Advanced digital temperature control for perfect seals every time.
  • Ease of Use: Simple setup and intuitive operation reduce training time.
  • Excellent Support: Comprehensive global technical support and readily available spare parts.
Does DGX offer custom sizes or OEM service?

Absolutely. DGX provides customized sealing dimensions, film widths, and power configurations based on your product size and factory layout. OEM and ODM services are available.

Do you offer customization for specific production line needs?

Yes. We offer several optional features, such as custom jigs/fixtures for irregularly shaped products, anti-static modules for sensitive electronics, and extended conveyor lengths for integration into fully automated lines. Contact us to discuss your specific requirements.

What is the warranty and after-sales service policy?

DGX offers a standard one-year warranty on parts and manufacturing defects. We provide detailed documentation, online support, and a global network of service technicians. Extended warranty and on-site training options are also available.
