Every year the same questions come up at baling time — how many bales will this roll of netwrap do, how many layers do I need, and what is it actually costing me per bale? The answers depend on roll length, bale size and how many layers you apply, but the working out isn't complicated once you have the right figures in front of you.

This guide covers netwrap rolls from 1,500m to 3,300m, silage stretch film by roll length and layer count, cost per bale for both systems, and the netwrap vs film wrap comparison. Use the Silage Net Wrap Calculator to work out exact figures for your bale size and layer count.

Quick Reference

at 6 layers — recommended

Netwrap — Bales Per Roll by Length and Width

Based on a standard 1.2m diameter round bale. Larger 1.5m bales use approximately 25% more netwrap per bale — reduce these figures accordingly. Always check your baler manual for the correct roll width before ordering.

Roll LengthWidthBales at 2 layersBales at 3 layers
1,500 m1.23 m~55–65 bales~37–43 bales
1,500 m1.25 m~55–65 bales~37–43 bales
3,000 m1.23 m~110–130 bales~73–87 bales

3,300 m1.28 m~118–140 bales~79–93 bales

Figures are approximate for 1.2m diameter bales. Actual bale count varies with bale diameter, baler overlap settings and roll quality. Use the Silage Net Wrap Calculator for your exact bale dimensions.

Silage Stretch Film — Bales Per Roll by Layer Count

Silage stretch film is the airtight layer that creates the fermentation environment. More layers mean better fermentation and fewer losses — the cost difference between 4 and 6 layers is small compared to the silage value protected.

Roll LengthWidth4 layers6 layers ✓8 layers
500 m500 mm~20–25 bales~13–17 bales~10–13 bales
750 m500 mm~30–38 bales~20–25 bales~15–19 bales
1,500 m500 mm~60–75 bales~40–50 bales~30–37 bales
500 m750 mm~30–38 bales~20–25 bales~15–19 bales

6 layers is the industry minimum recommendation. The ✓ column shows recommended standard.

How Many Layers of Silage Wrap Does a Bale Need?

Each layer of stretch film adds approximately 25 microns of barrier thickness. More layers mean a better oxygen barrier and significantly lower dry matter losses in storage. The cost of extra wrap is almost always less than the cost of the silage it protects.

4

4 layers — Absolute minimum

Ideal conditions only — bales stored for less than 3 months and used quickly after opening.

6

6 layers — Recommended

Standard recommendation for most UK farms. Good protection for storage up to 12 months.

8

8 layers — Best practice

Long-term storage beyond 12 months, or where bales will be stacked and handled multiple times.

10

10 layers — High risk sites

Exposed storage, history of bird damage, or premium forage crops where losses must be minimised.

Cost of Net Wrap and Silage Film Per Bale — UK 2026

Material costs only — excludes tractor, labour, wrapper depreciation and fuel. Contractor wrapping charge is total for labour and materials combined.

Roll costs are typical UK trade prices for 2026 and vary by supplier, quantity and region. Buy in bulk where possible — per-roll prices drop significantly on pallet quantities.

Netwrap vs Silage Film Wrap — Which Is Better?

Both systems are widely used on UK farms. The honest answer is that film-only wrapping gives better fermentation, while netwrap gives better physical protection. Many producers combine both — netwrap for shape and structure, film wrap over the top for the airtight seal.

🕸️ Netwrap

Advantages

  • Faster baling — no wrapper needed
  • Better bale shape and structural integrity
  • Easier stacking and handling
  • Lower cost per bale for the binding step
  • Works in wetter conditions

Disadvantages

  • Not airtight — needs film wrap over top for silage
  • Netwrap recycling required — extra cost and hassle
  • Can trap moisture if film fails

🎞️ Film Wrap Only

Advantages

  • Better oxygen barrier = better fermentation
  • Lower DM losses in storage
  • No netwrap recycling required
  • Cleaner opening — no net to remove before feeding

Disadvantages

  • Slower — wrapper makes more passes per bale
  • Bale shape less rigid — harder to stack
  • More vulnerable to bird and vermin damage
  • Higher material cost per bale

The combined system — most popular on UK farms

Most UK round bale silage is netwrapped first for shape and stability, then film-wrapped with 6–8 layers over the top. This gives the physical handling benefits of netwrap with the fermentation quality of film. The main downside is netwrap plastic waste, which must be collected and taken to an agricultural plastics recycler.

Mini Round Bale Netwrap

Mini round balers (producing 0.5m–0.8m diameter bales) use narrower netwrap than standard balers. The most common mini round baler netwrap widths are 0.9m and 1.0m, though some models take 1.23m or 1.25m standard width.

⚠️ Always check your baler specification before ordering

Mini round baler netwrap width is the single most common ordering mistake. The roll must match the baler's stated width exactly. Using the wrong width causes poor bale formation and netwrap waste. Check the existing roll on the machine or your baler operator manual before purchasing.

0.9m netwrap

80–100 bales

per 1,500m roll
