Company and Brand
For more than 30 years the Dover-Roll brand is recognized by consumers as a symbol of quality in garbage bags.
Dover-Roll is manufactured by Engetech Comércio e Indústria de Plásticos Ltda in a modern industrial complex, in the forefront of technological development in plastics processing.
We have a complete laboratory, where all production is rigorously inspected to meet National and International Standards.
Our products undergo various quality tests such as:
- Freefall Test
Hang the bag at maximum capacity for a few minutes at a certain height and drop it to the floor. In this test the bag should remain intact after the fall;
- Thickness Test
Measure the thickness of the bag with great precision using digital micrometer, to ensure that it is in compliance with specifications;
- Leak Test
Hang the bag at full capacity with liquid and after a few minutes, check if leaked or dripped;
- Opacity Test (Transparency)
Aims to measure the degree of opacity / transparency of trash bags, keeping them within the pre-set standards;
- Elasticity Test
Controls the elasticity of the plastic trash bag. This test aims to ensure adequate flexibility of the bag, so to a certain strength, stretch but not blow it.
