Common corrugated container styles

Compare three common box constructions to choose the right closure and protection for your shipment.

Regular slotted corrugated container

RSC: Regular slotted container

RSC boxes have flaps that meet at the center when closed. This versatile style works well for many shipping and storage applications.

Half slotted corrugated container

HSC: Half slotted container

HSC boxes have closing flaps on one end and an open top. Use them when contents extend above the box or when you plan to add a separate top closure.

Full overlap slotted corrugated container

FOL: Full overlap container

FOL boxes use long flaps that nearly overlap when closed. The added coverage helps protect shipments that may face rough handling.

What Is The Difference Between 32 ECT, 200 Lb. Test, and 275 Lb. Test Boxes?

Choosing the right cardboard box for shipping or packaging will help your contents survive the perils of everyday handling.
Eliminate shipping damages and costly returns by choosing the right box for your application.

  • UPS recommends 200 lb. test boxes for standard shipping.
  • 200 lb. test boxes are the most commonly used in industry and shipping.
  • 32 ECT boxes are a budget-friendly alternative for lightweight shipments.
  • 200# Test and 32ECT are interchangeable for most lighter and general-purpose applications.
  • However, 200 lb. test boxes are made with heavier paper and have 60% greater bursting strength than 32 ECT boxes.
  • Use 275lb. test boxes for heavier items and even greater protection.
  • 275-lb. test boxes are made with heavier paper and have 38% greater bursting strength than 200-lb. test boxes.

Comparing Bursting Test vs. Edge Crush Test

There are currently two tests used throughout the corrugated industry to determine strength.

1. Bursting (Mullen) Test = A measure of the force required to rupture or puncture the face of corrugated board and is measured by a Mullen Tester. 

2. Edge Crush Test (ECT) =  ECT is a measure of the edgewise compressive strength of the corrugated board. It is measured by compressing a small segment of the board on edge between two rigid platens or plates perpendicular to the direction of the flutes until a peak load is established. This is measured in pounds per lineal inch of load-bearing edge (lb/in) but usually reported as an ECT value (for example, 44 ECT).  

Box type Bursting test Minimum edge crush test Maximum load per carton
Standard 200# 32 ECT 40 lbs.
Heavy duty 275# 44 ECT 65 lbs.
Heavy duty, double wall 275# 48 ECT 80 lbs.
