How to protect net-wrapped bales

Hay or straw is baled by balers that form curved or rectangular bales of different sizes. Net or twine that conforms to the recommendations of the baler manufacturer is used to keep the baled crop in place. Polypak net is suitable for all types of popular balers.

The bales can be stored both on the farm and in the field. Without cover, rain falls on the outermost bales. If this happens, some of the forage becomes unusable, so it is advisable to cover the stacked bales when stored in the field.

Option 1: A canopy


Canopy is the most reliable and durable option for protecting bales with netting in the field, which you will get to use for many years. It is much cheaper than building a complete outbuilding or special warehouse, and more convenient and practical than using a tarpaulin or silage film as a shelter.


The canopy for protecting the bales should be high enough so that you can hide the bales under it. We have shown you how to do this correctly in the picture.


It is allowed to place the bales horizontally.

Option 2: Agrofiber


Agrofiber is the most common option for protecting bales from precipitation. It is made of polypropylene. The material is specially designed to cover bales. It is strong enough and has the ability to let in air without letting in moisture.


Usually, to cover the bales under the agrofibre, they are placed in several rows with a gradient shape. This is done to allow water to drain faster during rain.


The material will last 3-5 seasons. If it is used properly and stored in the off-season.

Option 3: tarpaulin or silage film


Small farms cover bales with tarpaulin or thick silage film. This option is only suitable for straw that will be used as bedding.

Film is cheaper than agrofibre. Tarpaulin has a higher strength and price than agrofibre. However, these materials have certain disadvantages:


– tarpaulin and silage film are not air permeable, condensation forms under them, and excess moisture promotes rotting and mold formation, so you can not cover bales with them completely without air access;


– animals and birds can damage the film, so it must be periodically checked for integrity and repaired;


– strong winds may open the bales, so if the storage place is far away from the farm this will not be immediately visible.


Option 4: Stretch film


Polypak stretch wrap is also used when making haylage. The hay bales are protected from the environment by the stretch wrap. Once wrapped, it is resistant to all weather conditions. Thanks to their small size, the bales are easy to transport.


As a result, the forage is of the highest quality, which cannot be achieved by the classical method of storage in trenches or mounds.


Every farmer decides for himself which bale wrapping method to use based on the objectives and capabilities of the farm.

You can buy qualitative netting at a good wholesale price with an order from 1 container. You can consult the manager about the conditions.
