How to choose PP anti-blocking masterbatch

Due to opening performance not good, it is necessary for PP film to PP anti-blocking masterbatch to improve it.

PP film is a common plastic film with excellent heat resistance, stretch resistance, toughness, transparency, etc. It is widely used in food, medicine, daily necessities, and other fields. However, due to the high density and dense molecular structure of the PP film, its opening performance is not good, and it is necessary to add an anti-blocking masterbatch to improve it.

This article will introduce how to choose a suitable PP anti-blocking masterbatch from the following three aspects.

The characteristics of PP film determine its requirements for an anti-blocking masterbatch. PP film has the following characteristics:

PP has a high melting point, generally above 160°C, so high-temperature processing is required.

The high crystallinity of PP film makes its molecular arrangement dense and difficult to form openings.

The transparency of the PP film is high, and an anti-blocking masterbatch is required to not affect its transparency.

The anti-blocking masterbatch of PP film is generally added separately. Common anti-blocking masterbatches include stearate, PE-wax, amides, and acrylic esters. When choosing an anti-blocking masterbatch, the following factors need to be considered:

The addition of the anti-blocking masterbatch should enable the PP film to achieve the desired opening effect, such as opening width, opening smoothness, opening shape, etc.

The processing temperature of PP film is high, so it is necessary to choose an anti-blocking masterbatch with a high melting point.

The addition of the anti-blocking masterbatch should not affect the transparency of the PP film.

It is necessary to consider the balance between the price of anti-blocking masterbatch and the effect of use.

Choosing the right PP blocking agent can increase production efficiency, reduce costs and improve product quality. Here are a few key points for choosing a PP opening agent:

The key to choosing a PP anti-blocking masterbatch is to consider its opening performance. Opening performance includes opening strength, opening speed, and opening flatness, etc.

The better the opening strength and speed, the higher the production efficiency, the better the opening flatness, and the better the product quality. Therefore, it is necessary to choose a PP anti-blocking masterbatch with good opening performance.

The use temperature of the PP anti-blocking masterbatch should match the melting temperature of the PP film, otherwise, problems such as poor opening will easily occur.

Therefore, when choosing a PP anti-blocking masterbatch, its applicable temperature range should be considered to ensure its stability during the production process.

The choice of PP anti-blocking masterbatch should consider the impact on PP film to avoid adverse effects, such as discoloration, deformation, and brittleness.

Therefore, a PP anti-blocking masterbatch that has little effect on the PP film should be selected.

The choice of PP anti-blocking masterbatch should consider the processing technology, such as extrusion speed, pressure, etc.

Because different processing techniques will affect the performance of the PP anti-blocking masterbatch, the PP anti-blocking masterbatch that matches the processing technology should be selected.

Selecting a suitable PP anti-blocking masterbatch is the key to producing high-quality PP film.

By choosing a PP anti-blocking masterbatch with good opening performance, wide applicable temperature range, little impact on PP film, and matching processing technology, production efficiency can be improved, costs can be reduced, product quality can be improved, and manufacturers can stand firm in the fierce market competition.
