Factors affecting the service life of plastic pallets
Source: kuda 2025-06-27
The main factors affecting the service life of plastic pallets include the following aspects:
1、 Material quality
Raw material quality: trays made of high-quality high-density polyethylene (HDPE) or polypropylene (PP) are wear-resistant, impact resistant, and chemically resistant, with a longer lifespan; The use of recycled materials or inferior plastic trays is prone to aging and damage.
Process difference: The trays produced by blow molding process are usually more acid and alkali resistant and have a longer lifespan than injection molded trays.
2、 Design Structure and Process
Reinforcement and structural design: Reasonable design (such as grid like surfaces and reinforcement bars) can improve load-bearing capacity and deformation resistance, reducing the risk of damage.
Size compatibility: The size needs to be adapted to the goods, forklifts, and transportation channels to avoid collision and wear caused by mismatch.
3、 Usage environment
Temperature and humidity effects:
High temperature: causes softening and deformation; Low temperature (such as below -20 ℃) is prone to brittle cracking, and it is necessary to use low-temperature resistant materials (such as HDPE) or add cold resistant agents.
UV exposure: accelerates aging and fading, shortens lifespan.
Chemical corrosion: Contact with corrosive substances such as strong acids and alkalis can significantly reduce the service life.
4、 Usage and load
Overloading and uneven load: Exceeding the dynamic and static load limits or uneven placement of goods can accelerate pallet deformation and breakage.
Forklift operation specifications: Misalignment of the forklift at the fork inlet or improper operation can easily cause damage to the pallet due to impact.
Stacking height: Stacking too high may crush the bottom tray and exceed the load-bearing limit.
5、 Maintenance and Storage
Regular cleaning and inspection: timely remove dirt, repair damaged parts, and prevent problems from worsening; Special industries (such as food) require disinfection and antibacterial measures.
Storage conditions: Outdoor storage requires rain and sun protection; When stacking, ventilation should be ensured to avoid excessive compression and collision.
6、 Other key factors
Transportation frequency: Frequent use accelerates wear and fatigue.
Identification management: Vague or missing identification may lead to misuse and overload.
Suggestions for extending lifespan: choose new material trays that are suitable for the environment; Strictly use according to the load limit; Standardize forklift operation; Avoid direct sunlight/extreme temperatures; Regular maintenance and cleaning; Reasonable stacking and storage.
