What are....Plastic Bags?

Plastic bags are a versatile, lightweight, cost-effective packaging solution used to store, protect, display, and transport a wide range of products. Commonly made from polyethylene (polythene) or polypropylene, plastic bags come in different sizes, thicknesses, and styles for retail, food packaging, manufacturing, warehousing, and industrial applications.

Plastic bags protect against dust, dirt, and moisture, while clear plastic bags keep products visible without opening the packaging. Depending on the material and application, you can seal them with heat, adhesive strips, tape, or resealable closures.

Types of Plastic Bags

There are several types of plastic packaging bags, each designed for different applications:

  • Polythene Bags (Poly Bags) – General-purpose clear plastic bags commonly used to package food products, hardware, components, and industrial goods. Available in a variety of sizes and thicknesses.

  • Polypropylene Peel and Seal Bags – Crystal-clear, glossy presentation bags with an adhesive flap, ideal for packaging greeting cards, stationery, clothing and retail merchandise.

  • Snap Lock Bags (Zip Lock Bags) – Resealable plastic bags featuring an interlocking press-seal closure, allowing repeated opening and closing. Ideal for small parts, food items and general storage.

  • Poly Tubing (Layflat Tubing) – Continuous rolls of polythene tubing that can be cut and heat sealed to create custom-sized plastic bags for products of different lengths.

  • Stand Up Pouches – Flexible packaging bags with a gusseted base that allows them to stand upright, commonly used for food, powders, coffee and retail products.

  • Plastic Shopping Bags – Carry bags designed for retail stores, promotional products and customer purchases.

What is the Difference Between Polythene and Polypropylene Bags?

Polythene bags (PE) are generally softer and more flexible, making them suitable for everyday packaging and industrial applications. Polypropylene bags (PP) typically offer greater clarity and a glossier appearance, making them popular for retail presentation and product display.

Plastic bag thickness is commonly measured in microns (µm), with thicker bags generally providing greater strength and puncture resistance.
