Top Quality Control Measures in Plastic Bag Manufacturing

Plastic bags may seem like simple products, but their making is not that simple. From the totes found at grocery stores to industrial, food-grade liners, the functionality of each bag has to be precise to exact standards—particularly when used for business, retail, or industrial applications. At A.N.S. Plastics Corporation, we know that quality is not a choice but it’s necessary. That’s why we have strict quality control standards in place to guarantee each plastic bag we send out of our plant functions effectively and satisfies the expectations of customers throughout New Brunswick, NJ and other areas.

In this blog, we’re going to detail the top quality control processes that go into producing quality plastic bags, highlighting how they safeguard your investment and reputation.

1. Raw Material Inspection

Quality starts with the raw materials. At A.N.S. Plastics, we utilize only high-quality-grade polyethene resins—mainly HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene). Each batch is checked at delivery for:

  • Purity and consistency
  • Moisture content
  • Melt flow index
  • Contaminants or abnormalities

By testing resin properties before the manufacturing process, we make sure that each bag has a good start.

2. Extrusion Monitoring

The extrusion process converts raw pellets into plastic film. Precision is what matters here, and minute deviations can result in weak points, unequal thickness, or lack of sealability. That’s why we have:

  • Temperature and pressure controls: Maintaining uniform melt and film formation.
  • Gauge control systems: Real-time monitoring and correction of film thickness.
  • Bubble stability monitoring: Maintaining the shape and size of the film bubble uniform to prevent material defects.

Our technicians at our New Brunswick plant constantly check the extrusion process to ensure consistency, strength, and quality.

3. Film Inspection

Even before the film is a bag, it goes through meticulous checking for:

  • Visual defects (streaks, pinholes, air bubbles)
  • Thickness consistency
  • Surface finish and clarity

We use automated sensors and manual checks to inspect the film and reject any rolls that don’t meet our strict standards. These early-stage inspections prevent defective film from progressing further in the manufacturing line.

4. Print Quality Assurance

Many New Brunswick businesses trust A.N.S. Plastics for custom-printed plastic bags. Whether it’s a logo, instructional text, or branded design, print quality matters just as much as structural integrity.
Our quality checks include:

  • Color matching to customer requirements
  • Ink adhesion and drying tests
  • Accuracy of print registration
  • Smudge and scratch resistance

We use flexographic printing technology and green-friendly inks to provide a professional appearance to every print job with durability during the bag’s lifetime.

5. Cutting and Sealing Accuracy

Each bag is cut and sealed by machinery that needs to run at high speed and high accuracy. To ensure every bag is within spec, we inspect for:

  • Clean, true-to-spec seals (no soft seams or scorching)
  • True dimensions (width, length, gusset depth)
  • Handle punch integrity (where applicable)

Soft seals or off-spec cuts can impair usability or safety. Our production staff checks random samples from each batch to guarantee tight tolerances and consistent performance.

6. Tensile and Load Testing

For plastic bags that will carry heavier loads or be used as an extra speciality (e.g., industrial liners, carry-out bags), we perform tensile strength and load capacity testing. They mimic actual use:

  • Pulling and flexing the bag in a controlled environment
  • Loading the bag to test its tear resistance
  • Dropping loaded bags to evaluate seal endurance

Testing like this guarantees our bags are functional standards for customers in retail, food service, and commercial industries in New Brunswick.

7. Environmental Resistance Testing

Most clients require bags to be durable in extreme environments—cold storage, UV light exposure, or exposure to moisture. To meet this need, we provide bags with special additives and perform:

  • Cold crack resistance tests
  • UV exposure simulation
  • Water resistance tests

Through environmental durability testing, we guarantee each product performs perfectly as needed within its targeted environment.

8. Final Batch Inspection and Documentation

Before a shipment leaves our warehouse, every order goes through final inspection and documentation. Our QA team:

  • Review batch samples for quality compliance
  • Verifies order specifications (size, quantity, packaging format)
  • Records test data and inspection results.
  • Labels each batch with traceability codes

This level of documentation gives our customers’ peace of mind—and the ability to trace every product back to its manufacturing data if needed.

9. Customer Feedback Loop

At A.N.S. Plastics Corporation, quality control doesn’t end in the factory. We remain close to our New Brunswick, NJ, clients and welcome feedback upon delivery. If a problem ever occurs, we perform a complete root-cause analysis and modify our procedures to avoid repeating it in the future.
