How to Measure Poly Bags for Effective Product Packaging

Choosing the right poly bag size is essential for businesses looking to protect their products while keeping shipping costs low. Accurate measurement ensures optimal protection and minimizes wasted material. Here’s an easy guide on measuring poly bags and selecting the best types to fit your needs.

Understanding Poly Bag Dimensions

Poly bag dimensions include width, length, height (or gusset), and lip. Consider the bag length, width, and height (or gusset) based on the product’s shape and packaging requirements.

• Width: Measure the width of your item. This measurement will directly measure the bag’s width for flat poly bags. If you’re using gusseted poly bags, measure the item’s flat width, then add the gusset width for bulkier items.
• Length: For a comfortable fit, the length should equal or slightly exceed your product’s length. For resealable bags like zip-lock plastic bags, include extra length to accommodate the closure.
• Height/Gusset: For extra-large plastic bags or bulky products, gussets are essential. Gussets provide side expansion, making pallet covers and gusseted poly bags ideal for items that need extra space.
• Lip: Measure the depth, leaving the additional flap from the bottom of the bag to the top of the seal closure.

Selecting the Right Poly Bag Type

Choosing the correct bag type affects presentation, storage efficiency, and ease of use in product packaging. Here’s a quick overview of the most common poly bag types:

Flat Poly Bags

• Description: Simple, single-layer clear flat bags without gussets, suitable for general packaging needs.
• Example P10280 : W = 8″, L = 18″ ➔ Outside Dimensions: 8″ x 18″
• Applications: Ideal for packaging food, clothes, parts, and items ideal for single-use packaging.

Gusseted Poly Bags

• Description: Bags with expandable sides offer a more spacious fit for irregularly shaped or bulky items.
• Example P10892: W = 8″, D = 4″, H = 15″ ➔ Outside Dimensions: 8″ x 4″ x 15″
• Applications: Perfect for retail packaging boxed goods or bulky products needing additional support.

Poly Bags on a Roll

• Description: Bags are perforated on a roll, making them easy to dispense and ideal for high-volume areas.
• Example P10964: W = 10″, L = 15″ ➔ Outside Dimensions: 10″ x 15″
• Applications: Great for warehouses and fast-paced packing environments.

Resealable Bags/Recloseable bags/ Ziplock bags

• Description: Featuring a zip-lock or press-to-seal closure, these resealable top bags allow secure, reusable storage.
• Example P1176: W = 20″, L = 24″ ➔ Outside Dimensions: 20″ x 24″
• Applications: Excellent for items needing frequent access, such as hardware, documents, or food items.

Wicketed Poly Bags

• Description: Bags grouped on a wicket, making them convenient for high-speed production settings.
• Example P11036: W = 12″, H= 19″, Depth = 4″ ➔ Dimensions: 12″ x 19″ x 4″
• Applications: Used in automated bagging for food and retail packaging lines. Commonly used for bread packaging.

Importance of Poly Bag Strength

Bag strength is measured in MIL, which ranges from lightweight 1-2 MIL bags for disposable items to heavy-duty 6 MIL bags for industrial needs:
