Meat container

Meat container

Description

Tons of bags are made of propylene polymerized to produce a thermoplastic resin. Abbreviated as PP, it is a crystalline polymer. PP is the lightest among the commonly used plastics, with a density of only 0.91g/cm3 (smaller than water). Among general-purpose plastics, PP has the best heat resistance, its heat distortion temperature is 80-100℃, and it can be cooked in boiling water

Toner bags for meat container bags are polymerized from propylene to produce a thermoplastic resin. Abbreviated as PP, it is a crystalline polymer. PP is the lightest among the commonly used plastics, with a density of only 0.91g/cm3 (smaller than water). Among general-purpose plastics, PP has the best heat resistance, its heat distortion temperature is 80-100℃, and it can be cooked in boiling water. PP has good resistance to stress cracking, and has a high bending fatigue life, commonly known as "100% plastic". The overall performance of pp is better than PE material. PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, and poor weather resistance. It has a post-shrinkage phenomenon. After demoulding, it is easy to age, become brittle, and deformed. PPR (pentatricopeptide repeats), also known as random copolymer polypropylene (PPR), has good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and has the unique high transparency of random copolymer polypropylene Advantages, FIBC manufacturer products can be widely used in the production of pipes, sheets, daily necessities, packaging materials, household appliance parts and various films.

Inspection standards for FIBC manufacturers:

1. Crop

1: The cutting specifications and dimensions must be cut according to the requirements of the production process sheet, and the length tolerance is<>

2: The cut section should not be skewed, the allowable deviation<>

3: The quantity of each bundle of the container bag manufacturer must be accurate and the allowable deviation<>

4: The position of the line should be accurate according to the requirements of the craft bill.

5: The defective rate is not allowed to exceed 5%0.

6: The cut semi-finished products must be kept clean and no dust is allowed.

2. Seam

1: Specification: allowable deviation below 1000mm ± 10mm, above 1000mm ± 15mm.

2: Appearance: The sewing needs to be straight, without needle breakage, broken needle, no floating thread, hanging needle, no less than 30mm return distance when the needle is raised and dropped, the container bag needs to be straight and straight, and there should be no obvious missing Warp Shaowei, there must be no obvious defects, the printed pattern is clear and the position is correct.

3: Lifting rings: The lengths of lifting rings, suspenders and lifting lugs should be the same as required, and the overlap should be even and straight.

4: Stitch: Two or more stitches are required. It is strictly forbidden to overlap and press together. The distance between rows is 2-4mm. The reinforcing cloth connecting the sling and the bag body has a 10mm seam from the side, horizontal and vertical, and other parts are sutured strictly according to the requirements. The basic standard of the needle code 10cm requires 9-12 needles (specifically according to the size of the needle code required by the user).

5: Hygiene: Wire head, hair, dust, stains, oil spots, debris, etc. are strictly prohibited inside and outside the bag.
