Hulead Packaging teaches you how to purchase stretch film professionally

First, clear use requirements: identify the type of product

Before purchasing, it is necessary to first confirm the compatibility between the usage scenario and the equipment:

Hand-wound film: Suitable for small batches, irregular-shaped goods, and supplementary packaging

Machine-wound film: Suitable for automated production lines, and requires a pre-stretched model

Specialized products: Weather-resistant type (for outdoor use), strong adhesive type (smooth surface), anti-static type (for the electronics industry)

Two, key parameter analysis: understand the technical indicators

The four core parameters determine the packaging effect:

Thickness selection: For regular goods, choose 20-23 μm; for heavy-duty pallets, choose 25-30 μm

Stretch rate control: Pre-stretched film selects 200%-250%, ordinary film selects 150%-180%

Width matching: Select the standard width of 450mm-500mm according to the pallet size

Adhesion test: Through handheld testing to determine the initial and final adhesion performance

Three, supplier evaluation system: the big four audit dimension

Hulead Packaging suggests evaluating suppliers through the following four aspects:

Production Capacity: Whether they have their own production lines and the ability to control raw materials

Quality Certification: The status of obtaining international certifications such as ISO9001 and SGS

Testing Equipment: Whether the laboratory is equipped with testing instruments like tensile testers and moisture permeability testers

Service Network: The coverage of after-sales support and technical services

Four, cost optimization: full cycle evaluation

Scientific procurement should focus on three major costs:

Unit cost: Compare the unit prices of products of the same specification

Usage cost: Calculate the actual consumption per tray

Hidden cost: Includes downtime losses, rework rates, storage occupancy, etc., which are indirect costs

Step five, sample testing process: five validation method

Recommended standardized testing process for Hulead packaging:

On-site machine testing: Conduct a 48-hour continuous test on the actual equipment

Parameter recording: Record data such as uniformity of stretching, breakage rate, packaging efficiency, etc.

Environmental simulation: Simulate extreme transportation environments such as high temperature and high humidity

Comparison analysis: Conduct parallel comparison with the currently used products

Comprehensive evaluation: Organize joint review by the procurement, production, and logistics departments

Six points, procurement contract, guarantee a long-term cooperation

Key provisions that require special attention:

Process and time limit for handling quality disputes

Minimum inventory guarantee and emergency supply mechanism

Regular quality inspection and data sharing mechanism

Technical upgrade and product iteration support provisions

Through the above systematic procurement method, enterprises can reduce packaging costs by 15% to 25%, and simultaneously increase the packaging qualification rate to over 99%.
