Stretch film packaging machine process guide

Stretch film packaging machine process flow guide is a kind of packaging equipment widely used in the packaging industry for various food, medicine, industrial products, etc. Its main feature is to use high-strength stretch film as the material to completely cover the product to achieve the effect of ensuring product quality and beauty. In the following, we will take the Stretch Film Packaging Machine Process Flow Guide as the theme and give a detailed introduction through examples.

Stretch film packaging machine is a kind of high-efficiency packaging equipment. The following aspects should be paid attention to during operation:

1.Choose the packaging film correctly: Different packaging films have different materials, thicknesses and stretching ratios. Select the corresponding sales packaging film according to different products to ensure the quality and appearance of the product.

For example: when packaging biscuits, PET/PE double-layer stretch film should be used. Under the premise of ensuring airtightness, it can not only prevent the state of cakes and bread from deteriorating, but also ensure the bright color of the product

2. Set a reasonable packaging temperature: The packaging temperature directly affects the fastness of the stretch film. Setting a reasonable packaging temperature can ensure the stability and aesthetics of the packaging effect.

For example: when packing strawberries, the packaging temperature should be controlled at about 110°C-120°C, which can ensure that the bonding fastness between the stretch film and the strawberry surface is enhanced, so that the strawberries can maintain a good fresh-keeping effect.

3. Control the packaging speed: The packaging speed affects the ductility and tearability of the stretch film, and the appropriate speed can ensure the packaging effect.

For example: when packing instant noodles, the speed of the packaging machine should be controlled at about 30 m/min, so as to ensure that the stretch film is tightly packed, prevent the product from scattering, and will not be too tight, causing the surface of the instant noodles to deform.

4. Accurately adjust the preheating time: The preheating time is very important and affects the stretching effect of the stretch film.

For example: when packing garlic, the preheating time should be set to 3-5 seconds, and the packing speed should be controlled at about 20 m/min, so that the stretch film can be fully stretched, so that the surface of the garlic can be completely sealed, and the sealing effect of the garlic can be ensured. .

2. Related issues

When using the stretch film packaging machine, you will encounter some problems. The following are common solutions to the problems:

1. The problem of burrs: The problem of burrs refers to the phenomenon of burrs in the stretch film during the packaging process.

Solution: Adjust the slitting speed and the angle of the cutting knife to adapt to the packaging of different materials.

2. Pull spot problem: The pull spot problem refers to subsurface creases or pull marks on the surface of the stretch film during packaging, which will reduce the aesthetics of the product.

Solution: Adjust the stretching ratio of the packaging machine, appropriately increase the warm-up time, avoid excessive stretching, and pack under appropriate pressure, which can effectively avoid the occurrence of pulling spots.

3. Partial curling problem: The local curling problem refers to the phenomenon of local stretch film curling during packaging, which affects the overall aesthetics of the product.

Solution: Adjust the crimping force of the packaging machine, and increase the stretching degree if necessary to ensure that the stretch film is stretched evenly on the entire surface, and avoid local crimping problems.

3. Maintenance

The quality of the maintenance operation directly affects the normal operation of the packaging machine, which requires regular cleaning and maintenance.

1. Regularly clean the rollers and sliding bearings, and add lubricating oil;

2. Clean food residues and dust, and regularly disinfect the packaging machine;

Check the connecting parts and transmission mechanism, lubricate and repair if necessary;

4. Clean the sewage pipes of the packaging machine to prevent environmental pollution.

In short, the stretch film packaging machine is widely used in the modern packaging industry, and it is one of the important equipment to ensure product quality and beauty. When using stretch film packaging machines, we need to pay attention to the key points of operation, solve related problems and perform regular maintenance. Only in this way can we better improve the efficiency and effectiveness of packaging production and meet customer requirements for commodities.
