What Are The Test Methods For Commonly Used Feed Woven Bags?

During the production and sales of feed, except for some of the feed directly sold to large farms, it is transported by cans.

The rest need to be wrapped in the packaging bag before they can be sold and transported.

The quality of the packaging bag not only affects the quality of the feed, but also reflects the quality control level of the factory.

Good quality packaging bags have a positive impact on improving the brand image of the product.

Let's talk about the testing method of feed woven bag commonly used in feed factories.

1. Exterior test

The appearance test should be carried out under natural light.

1. Broken wire: The sum of the same meridians and weft lines should be less than 3.

2. Cleaning: Obvious oils of more than 100 square millimeters are not allowed, and obvious oil pollution below 100 square millimeters must not be more than 3 places.

3. Switching: Patriotic degradation, disconnection, and non -sewing rolls are not allowed.

4. Cut edge: Sanbian is not allowed.

Second, line density

1. Line density requirements are as follows:

Allowing loading capacity 10-20 (kg), density X latitude density 32x32 (root/100 mm);

Make loading capacity 21-30 (kg), density x werely density 36x36 (root/100 mm);

Allowing loading capacity 31-50 (kg), density x werely density 40x40 (root/100 mm);

Allowing loading capacity 51-60 (kg), density x werely density 48x48 (root/100 mm);

2. Detection method:

Found the bag, and set up 100mmx100mm blocks in the upper and lower diagonals of the bag.

The outer side of the block is 100mm from the edge of the bag. Visually, the meridians and weft roots in the block are taken to take the average value. When calculating, when the point is less than one, press one.

The permitted error of the line density and weft density is 1/10mm.
