Box Maker’s Certificate (BMC) – Carton Quality Assurance Seal
Category:
Package
The Box Maker's Certificate (BMC) , commonly also referred to as the carton quality assurance mark, is a stamp printed on the shipping container that indicates the box meets specified requirements. The certificate identifies the box manufacturer, contains detailed specifications about the box, and serves as a mark of compliance. The Box Maker's Certificate also specifies the maximum load the box can withstand, based on the material composition and construction.
While the Box Maker's Certificate is not mandatory, it is important for both box manufacturers and product manufacturers. For the box manufacturer, it demonstrates that the boxes they produce meet the required strength specifications. For the companies purchasing the boxes, it provides assurance that the packaging can be relied upon to bear its intended load.
There is a quality assurance seal on the cardboard box. 2 Version type
Mullen-Rate Box Maker's Certificate
The Mullen test measures the wall strength of the box. This determines the pressure required to puncture or rupture the box wall (hence its alternate name, the bursting test).
Understanding the Mullen-Rate Box Maker's Certificate:
◉ Box Manufacturer: The company that manufactured the box in your possession. It is always listed at the top of the outer circle.
◉ Board Construction: The thickness and strength of the box sidewalls, listed as single-wall, double-wall, or triple-wall corrugated board.
◉ Bursting Test: The resistance of the box wall to puncture or rupture. The most common Mullen-rated boxes have a burst strength of 200 lb/in².
◉ Minimum Combined Weight Facings: The total combined weight of the linerboards (facings) before they are cut into boxes, expressed in pounds per thousand (M) square feet. In the example above, the combined weight of the uncut liners is 84 lbs per M sq. ft.
◉ Size Limit: The sum of the box's external dimensions. This information is useful for storage and shipping purposes, such as planning pallet loads or calculating dimensional weight.
◉ Gross Weight Limit: The maximum allowable total weight of the box and its contents. Boxes loaded beyond the listed weight are susceptible to damage, as the box's structural integrity becomes compromised.
◉ City & State: The location where the box was manufactured. It is always listed at the bottom of the outer circle.
Edge compression grade (ECT Rate) Carton Quality Assurance Seal
The Edge Crush Test (ECT) evaluates the stacking strength of the box. This determines how much compression the box can withstand before being crushed. Since most shipping today is accomplished by stacking boxes on pallets, this is an ideal strength test for shipping individually boxed products and commodities.
Understanding the ECT-Rate Box Maker's Certificate:
◉ Box Manufacturer: The company that manufactured the box in your possession. It is always listed at the top of the outer circle.
◉ Board Construction: The thickness and strength of the box sidewalls, listed as single-wall, double-wall, or triple-wall corrugated board.
◉ Edge Crush Test (ECT): The vertical compression strength of the box wall. The most common ECT-rated boxes have a strength of 32 lb/in, listed as 32 ECT.
◉ Size Limit: The sum of the box's external dimensions. This information is useful for storage and shipping purposes, such as planning pallet loads or calculating dimensional weight.
◉ Gross Weight Limit: The maximum allowable total weight of the box and its contents. Boxes loaded beyond the listed weight are susceptible to damage, as the box's structural integrity becomes compromised.
◉ City & State: The location where the box was manufactured. It is always listed at the bottom of the outer circle.
