Grapes Bagging Machine Guide: How to Choose the Right Color Bags & Benefits of Bagging

Why Every Large Orchard Grower Needs a Grape Bagging Machine？

Grape bagging, also known as grape protection bags or grape bunch bags, is an ideal solution for protecting grapes on the tree before harvest. Grape bagging technology has become an ideal alternative to conventional cultivation in organic grape production worldwide. It effectively protects grapes nearing maturity from bird attacks, pests and diseases, and damage from wind, rain, and sunlight, which can reduce yields and cause quality variations. This protection also means that grape bagging prevents pesticide contamination of the fruit.

A single grape bagging machine can produce high-quality grape bags to meet the bagging needs of large-scale growers.

What are the advantages of grape bagging, which allows more and more growers to bag grapes?

1. Significant pest and disease control effectiveness

With the continuous development of tropical and subtropical fruit cultivation, the application of fruit bagging technology has also expanded, achieving significant pest and disease control results.

Grapes bagged with this technology typically only require pesticide spraying during flowering and before bagging. Bagging isolates the grapes from the outside environment, preventing the spread of most pathogens and the invasion of insects and flies. This reduces pest and disease exposure and reduces the frequency of pesticide applications. The barrier effect of the bag prevents sprayed pesticides from directly contacting the fruit surface, significantly reducing pesticide residues in the fruit.

The pest and disease control effectiveness of bagging on various fruit trees averages 81.1%, a significant achievement.

2.Grape bagging provides excellent protection and ensures a high-quality appearance

Grape paper bags feature excellent strength, high toughness, and impermeability, effectively protecting against wind, insects, and birds. Once bagged, the grapes' surface is protected from environmental factors. The temperature, humidity, and light intensity inside the bags are relatively stable, maintaining a smooth skin and enhancing the fruit's commercial value.

3.Improving the Rate of High-Quality Fruit

High-quality fruit often has better market competitiveness, and bagging significantly improves the quality of grapes produced, which is crucial for increasing the value of the fruit.

Color Selection: Choose the appropriate bagging type based on the grape variety

Now is grape bagging season. For vineyards growing popular grape varieties like Red Globe or Kyoho, Investing in a high-quality fruit bagging machine will pay off in improved fruit quality and reduced losses.

The grape bagging machine you choose should be able to select different bag colors based on the grape variety.

Suitable for red/purple grapes (Red Globe, Kyoho)

- Recommended bagging: White

Benefits:

- Allows optimal light penetration for even coloring of the grapes

- Prevents overheating (unlike dark bagging)

- 120-150 g/m² thick paper resists tearing

Suitable for green grapes (Sun Muscat, Thompson)

- Recommended bagging: Blue/green or tricolor paper

Benefits:

- Filters specific wavelengths of light to prevent sunburn

- Maintains a vibrant green color

- Typically weighs 90-110 g/m² for improved air permeability

Applicable grapes bagging machine:

It is a medium-sized fruit bag making machine that can produce grape bags, mango bags, citrus bags, lemon bags and other fruit bagging production speed 200-400 pieces/minute, voltage 200V, 380V optional.

Grapes (primarily Red Globe) should be stored in specialized single-layer grape bags, typically measuring 200-280 mm * 330-360 mm.

For low-light conditions, the bag paper should be 29-32 gsm. For outdoor conditions with strong sunlight, the bag paper should be 33-35 gsm.
