Silage Bags And Grain Bags

TSPLAS silage bags are large plastic tubes used to store animal feed and grain. The bag is filled and the air squeezed out to create a vacuum seal, and the film is UV resistant with high puncture resistance for outdoor storage on a working yard.

Overview

What This Product Is Built To Do

A silage bag is the cheapest way to add sealed storage without building anything. The bag is filled with the crop, the air is squeezed out, and the vacuum seal that forms keeps oxygen away from the feed, which is what stops the bacteria and fungi that cause spoilage. TSPLAS bags are made from a plastic formulated for the job: UV resistant so the bag survives a season in the open, and with high puncture resistance because a bag lives on a yard where machinery moves. Bags can be sited wherever the crop is, so storage follows the harvest rather than the other way around.

Key Benefits

  • Vacuum seal stops the aerobic spoilage that costs dry matter
  • No civil works, so storage capacity can be added in a single season
  • UV resistant film for outdoor siting
  • High puncture resistance for handling on a working yard
  • Feed quality held for the herd, which is where the return actually shows

Problems It Solves

  • Bunker silo capital cost competing with feed spend
  • Oxygen in a poorly sealed store spoiling feed
  • Dry matter lost each time feed is moved to rented storage
  • Storage capacity that cannot flex with a good harvest year

Who It Is For

  • Dairy and beef operations growing herd size
  • Grain growers holding crop on farm
  • Contract bagging operators
  • Farm supply importers and distributors

Application Scenarios

  • Corn silage and haylage storage on an expanding dairy
  • On farm grain holding after harvest while waiting on price
  • Contract bagging services moving between farms
  • Temporary storage when the bunker is already full

Comparison

How It Compares With The Alternatives

Bunker siloA bag needs no concrete, no walls and no planning, and the sealed face exposed at feed out is far smaller.
Baled silage with wrap filmBags suit a single yard storing large tonnage in one go. Wrapped bales suit feed that has to be moved or traded in units.
Grain binsBags let a grower add holding capacity in a strong harvest year without committing to permanent steel.
Use Guide

Getting The Specification You Paid For

  • Fill to the recommended level and leave room for proper compaction
  • Use a high quality silage inoculant to promote fermentation and reduce spoilage
  • Seal the bag tightly at both ends and site it dry, cool and shaded
  • Monitor the bag regularly for signs of spoilage and adjust as needed
  • Patch any tear the day it appears so the vacuum seal is not lost
FAQ

Silage Bags Questions

How does the bag actually preserve the feed?

The bag is filled and the air is squeezed out to create a vacuum seal. That seal prevents the growth of the unwanted bacteria and fungi that spoil feed.

Can the bags be stored outdoors?

Yes. The plastic is UV resistant and has high puncture resistance, which is what outdoor siting on a working yard demands.

What size bag do I need?

Bag diameter must match your bagging machine and the length follows your tonnage. Send the machine model and the tonnage with your enquiry.

Can the same bag hold grain?

Yes, the same product is used for grain storage as well as corn silage and haylage.

Is there a minimum order?

No. There is no minimum order quantity, though volume changes the shipment cost considerably.
