Efficient Packaging Production Process | HAPLAST Vietnam Factory

The Art and Science of Packaging Production at HAPLAST

In today’s fast-moving world of global trade, packaging production is more than just a technical process — it’s a balance between art, precision, and sustainability. The right packaging doesn’t only protect products; it reflects the brand’s values, ensures supply chain efficiency, and builds trust across markets.

At HAPLAST GROUP, we combine advanced technology with decades of manufacturing expertise to deliver packaging that meets the highest international standards. From material mixing to film blowing, printing, cutting, and final packing, every step in our packaging production process is precisely monitored, reflecting both craftsmanship and responsibility.

Here’s how HAPLAST transforms raw materials into high-performance packaging products trusted by global brands — a process where innovation and sustainability go hand in hand.

1. Mixing – The Foundation of Packaging Production

Every great product starts with the right mix.

At HAPLAST, raw materials — including virgin and recycled plastic resins — are blended in high-speed mixers for 40–45 minutes per batch. This ensures a consistent base for the next steps in the packaging production process.

Depending on each customer’s requirements, we offer:

• Virgin material bags (100% new resin) for food-grade or transparent packaging.
• Recycled-content bags with 10–70% recycled resin for cost efficiency and sustainability.

2. Film Blowing – Building the Packaging Base

The next stage of packaging production involves film blowing. The mixed materials are melted and extruded through high-precision film-blowing machines to form tubular film.

This process defines the bag’s thickness, clarity, and strength.

• The film passes through adjustable cooling systems to meet width and micron specifications.
• Textured surfaces can be created using a special rough roller.
• The finished film is rolled — forming blown rolls ready for printing or cutting.

Any production scrap is immediately collected and recycled within HAPLAST’s closed-loop packaging production system.

3. Printing – Up to 6 Colors of Precision

Our modern flexographic printers handle up to 6 colors per run, ensuring brand consistency and high-quality visuals. Each film roll passes through multiple printing cylinders — one for each color — to achieve perfect registration and sharpness.

If printing is not required, the film moves directly to the cutting stage, maintaining production efficiency. This step is a key part of HAPLAST’s packaging production excellence, ensuring custom designs that reflect each brand’s identity.

4. Cutting – Turning Film into Functional Bags

This is where the magic happens — converting rolls into bags of all shapes and types.
HAPLAST operates more than 10 specialized cutting machines, designed for various bag categories:

• T-shirt bags (Hemingston line)
• Flat and block header bags
• Luxury shopping bags (Drawtape, Soft loop, Heat patch)
• Core and coreless roll bags (C-fold, star-fold, double-fold, etc.)

Each machine is calibrated for cutting speed, heat, and sealing temperature to match specific bag dimensions and features. The cutting process ensures precision while minimizing waste — and any residual material is again directed to the recycling system.

5. Packing – Final Check Before Shipment

After cutting, the bags are counted, stacked, or rolled according to customer packaging requirements. Our QC team conducts continuous inspections during packing to ensure:

• Correct thickness and dimensions
• Clean seals and print quality
• Accurate labeling and weight

Only products that pass quality control are sealed, labeled, and moved to the finished goods warehouse. Non-conforming items are set aside for reprocessing.

6. Recycling – Closing the Loop

At HAPLAST, sustainability is integrated into every step. All waste from blowing, cutting, and packing stages is collected, cleaned, and reprocessed into recycled pellets — used again in producing eco-friendly packaging.

This circular model minimizes material waste and supports global environmental goals — aligning with EU PPWR and U.S. SB54 regulations.

7. Material Quality Options by Market

HAPLAST adapts its material mix to match different market standards:

This flexibility allows customers to optimize cost, performance, and compliance for their own market needs.
