M-Line’s plastic case is considered among the best the industry offers. Rugged, lightweight, reusable and attractive, they are designed and manufactured by SKB to take a lot of punishment while cradling their contents in ultimate safety.    ## Unrivaled Among Plastic Case Manufacturers SKB, which ranks among the top plastic case manufacturers, makes plastic cases using various technologies, giving our customers a range of choices when deciding on a case. Injection molding produces innovative hard shell case products and many auxiliary parts. Roto-mold cases are designed for maximum protection and can withstand significant impacts during transport. Vacuum forming or thermal forming uses acrylonitrile butadiene styrene (ABS) or polyethylene (PE) processed in sheets and heated, then vacuum-formed around aluminum castings to take the shape of the mold. ## Indestructible, customizable, field-replaceable!  Our SKB iSeries cases are virtually indestructible. These cases are waterproof, dustproof (meeting US military equipment standard MIL-STD 810H), and lighter and 2.8x stronger than the competition. iSeries cases are designed to last a lifetime!   All the cases M-Line offers feature customizable interiors. We can customize foam inserts for your product’s perfect fit. They also have field-replaceable hardware: SKB's patented industry-best Trigger Latch® System, cushion-grip handles, and wheels are all field-replaceable.   The plastic cases M-Line provides to customers are designed to meet your needs and thoroughly tested to provide years of problem-free service. Available in a wide range of shapes and sizes, SKB cases are the only ones made with 100% virgin resin and all are made in America.    To learn more about M-Line’s plastic case manufacturers such as SKB, call (800) 659-8559 or [contact us.](https://m-line.com/contact-us/) [Product Packaging](https://blog.m-line.com/tag/product-packaging) ## Read On ### [Custom Cut Foam Cases When shipping sensitive, fragile, or expensive products, a cardboard box filled with packing...](https://blog.m-line.com/custom-foam-cases) ### [How to Choose Protective Packaging Materials Every year, manufacturers lose thousands of dollars due to shipping damage such as crushed...](https://blog.m-line.com/how-to-choose-protective-packaging-materials) ### [Product Packaging Glossary When you’re new to the packaging world, there are a lot of terms to learn.
