PP Spunbond Nonwoven in Fruit Bag Application

The Problem Every Fruit Grower Knows Too Well

You've spent months:

• Pruning

• Watering

• Fertilizing

• Watching the weather like a hawk

Then comes harvest day. And you find:

• Bird pecks

• Sunburn scars

• Insect stings

• Scratches from branches rubbing in the wind

Perfect fruit on the inside. Ugly fruit on the outside.

And ugly fruit = lower price. Or worse — rejected by the supermarket buyer.

The Solution That's Been Hiding in Plain Sight

Spunbond Polypropylene (PP) Nonwoven Fruit Protection Bags.

They look simple. But behind that soft, white fabric is serious agricultural engineering.

The Two Weights That Work Best for Orchards

Not every bag is right for every fruit. Here's how to choose.

100 gsm – The All-Rounder

Perfect for: Apples, pears, peaches, mangoes, guavas, citrus.

• Why 100gsm? Light enough to let in 70-80% of natural light (fruit colors beautifully). Strong enough to withstand wind and rain for 2-3 months in the tree.

• Tensile strength: ≥ 120 N/5cm (won't tear when you tie the bag closed).

• Breathability: 800-1200 mm/s (air flows freely — no mold).

150 gsm – The Heavy-Duty Protector

Perfect for: Pomegranates, pomelos, large mangoes, high-altitude orchards (intense UV), or longer growing seasons.

• Why 150gsm? Thicker fabric = more UV protection + higher mechanical strength. Use this when you need the bag to survive 4-6 months on the tree through monsoon rains and strong winds.

• Tensile strength: ≥ 220 N/5cm (almost tear-proof).

• Breathability: 600-1000 mm/s (still breathable, just slightly less airflow — fine for larger fruit with thicker skins).

The "Invisible" Feature That Matters Most: Heat Buildup

This is where cheap plastic bags fail — and spunbond PP wins.

Plastic bags (polyethylene) act like mini greenhouses. On a 35°C day, the inside of a plastic bag can reach 50°C+. That cooks the fruit. You get soft spots, off-flavors, and premature ripening.

Spunbond PP is different. Because the fabric is porous:

• Hot air escapes

• Cool air enters

• The fruit stays within 2-3°C of outside temperature

Result: Naturally ripened fruit. Better sugar content. Longer shelf life after harvest.

Real Grower Results (What We've Seen)

How to Use Fruit Protection Bags (The Right Way)

Step 1: Thin the fruit
Leave only the best 1-2 fruits per cluster. Don't waste bags on fruit you'll thin later.

Step 2: Time it right
Bag within 30 days of fruit set — before insects find your crop.

Step 3: Bag correctly
Place the bag over the fruit. Gather the opening around the stem. Secure with the built-in wire tie or staple (don't crush the stem).

Step 4: Leave a small gap
Don't seal it airtight. A small opening at the bottom lets water drain and air circulate.

Step 5: Remove before harvest
For most fruits, remove bags 1-2 weeks before picking. This allows final color development (especially for red apples and peaches).

What Smart Buyers Look For (Technical Checklist)

If you're sourcing spunbond nonwoven for fruit bags, here's your quality checklist:

✅ Virgin PP (recycled material degrades faster in UV — not good for 3 months in an orchard)
✅ UV stabilizers (ask us — we add them on request)
✅ Consistent weight (100gsm ±5 / 150gsm ±7)
✅ No pinholes (one tiny hole = one insect entry point)
✅ Good tear strength (growers tie bags tight — weak fabric rips)
✅ Breathable but not too breathable (800-1200 mm/s for most fruit)

Cost vs. Value: Do Fruit Bags Pay Off?

Let's do the math.

Most growers recoup the cost of the bag within the first 2-3 trees.

The Bottom Line

You can spray chemicals. You can net the whole orchard. Or you can do what smart growers everywhere are doing:

Bag the fruit. Protect the profit.

Spunbond PP fruit bags are:

• Reusable (some growers rinse and reuse for 2-3 seasons)

• Biodegradable over time (PP breaks down with UV exposure — but slowly)

• Labor-efficient (one person can bag 500-1000 fruits per day)
