Antioxidants
Elastic stretch film roll Stabilize molecular structure: Antioxidants mainly inhibit the oxidation reaction of the stretch film during processing and use by capturing free radicals, thereby stabilizing the molecular structure of the polymer and preventing the degradation and cross-linking of the molecular chain. This helps to maintain the original performance of the stretch film so that the stretch ratio will not be reduced due to oxidation.
Elastic stretch film roll Indirect influence on tensile properties: In some cases, antioxidants may interact with other components in the polymer material, or produce certain physical or chemical adsorption on the polymer chain, thereby affecting the mobility and aggregation structure of the molecular chain to a certain extent, and indirectly affecting the stretch ratio of the stretch film.
Fillers
Elastic stretch film roll Reinforcement effect: Certain fillers such as calcium carbonate and talcum powder, if the particle size is appropriate and the dispersion is uniform, can form a good interface with the polymer matrix and play a reinforcing role. During stretching, the filler can bear part of the external force, so that the stretch film as a whole can withstand greater tensile force, which may increase the stretch ratio.
Transparent plastic packaging film Dilution effect: If the amount of filler added is too much, it may play a dilution role in the polymer matrix, reduce the interaction between polymer chains, and cause the mechanical properties of the stretch film to decrease and the stretch ratio to decrease.
When buying a Industrial transport stretch film Transparent plastic packaging film, there are many factors to consider, such as material, specifications, and performance. The following are detailed purchase instructions:
Clear use requirements
Transparent plastic packaging film Type of packaging items: Consider whether the packaged items are regular or irregular in shape, solid, liquid, or fragile. For example, when packaging fragile items such as glass products, you need to choose a Industrial transport stretch film with good cushioning performance and high tensile strength to provide adequate protection; when packaging liquid products, ensure that the stretch film has good sealing and puncture resistance.
Packaging environment and storage conditions: If used or stored in a high temperature environment, you should choose a stretch film with good high temperature resistance to prevent softening, deformation, etc. during use or storage; in a humid environment, you need to consider the moisture-proof performance of the Industrial transport stretch film; if you need long-term storage, you also need to pay attention to its aging resistance.
Packaging method and efficiency: If it is manual packaging, you can choose a stretch film with thin thickness, good softness, easy stretching and operation; if it is machine packaging, you need to choose a matching stretch film according to the model and performance of the packaging machine, such as a suitable stretch ratio and toughness to ensure a smooth and efficient packaging process.
