The full name of the heavy bag automatic packaging machine is the heavy-duty large bag automatic continuous packaging machine (large bag sealing machine).

① The concept of heavy bags:

In the packaging industry, weight and lightness, size and smallness are relative concepts, and the general weight range is defined as follows

Small packaging ≤ 5Kg

Large packaging of 5-20kg

Heavy bag packaging 25-50Kg

Ton packaging (extra large packaging) ≈ 1t

② The functions that a heavy bag automatic packaging machine should have are:

1. The heavy bag automatic packaging machine should be suitable for packaging powders, granules, and small pieces of materials.

2. The heavy bag automatic packaging machine should be suitable for models with multiple packaging methods.

3. The heavy bag automatic packaging machine is suitable for the needs of large-scale production enterprises.

4. The heavy bag automatic packaging machine has high working efficiency, and the continuous packaging line speed can reach 7-10m/min.

5. The head of the heavy bag automatic packaging machine can be adjusted up and down to adapt to the height of packaging bags of different heights.

6. The heavy bag automatic packaging machine is suitable for packaging environmentally friendly packaging bags.

7. The so-called automation of heavy bag automatic packaging machine means that it must meet a high degree of automation.

8. The heavy bag automatic packaging machine can be matched with automated packaging production lines.

9. Heavy bag automatic packaging can be produced in harsh environments such as toxic materials, corrosive materials, and severe dust.

10. The heavy bag automatic packaging machine reduces the labor intensity of operators and ensures the physical health of workers.

③ Selection of packaging materials for heavy-duty large bags:

A. Degradable, recyclable, and pollution-free environmentally friendly materials:

1. Paper bags or multi-layer paper bags (usually made of kraft paper or Dorian paper).

2. Plastic bags.

3. Paper bag lined with plastic bag.

4. Paper bag lined with aluminum-plastic composite bag.

5. Hot melt adhesive tape or wrinkled paper tape, mostly made of kraft paper; The hot melt adhesive coating is made of colorless, non-toxic, and biodegradable polyvinyl alcohol.

B. Recyclable and reusable non degradable materials: plastic woven bags, plastic films and plastic woven composite bags, paper plastic composite bags, paper plastic woven composite bags.

④ Quality requirements for heavy-duty large bag packaging and requirements for special materials:

1. Heavy duty large bag packaging can achieve additional environmental performance of the product: biodegradable, recyclable, and pollution-free.

2. The strength performance of heavy-duty large bag packaging: it can withstand high tensile strength and anti compression strength.

3. Sealing performance of heavy-duty large bag packaging: high airtightness without leakage.

4. Sealing fastness performance of heavy-duty large bag packaging: The sealing method must have stable and reliable fastness.

5. Shielding performance of heavy-duty large bag packaging: For materials that require special requirements such as avoiding light and radiation, they must have shielding effect.

6. Removable performance of heavy-duty large bag packaging: The design of the packaging bag should be easy to unpack and dump.

7. Stackable performance: It is not easy to slip color when stacking.

8. Economy: Under the requirements of reliability and environmental protection, strive to meet the requirements of economy as much as possible.
