In the processes of product circulation, storage, transportation, and terminal sales, packaging not only fulfills the basic function of product protection but also directly influences brand image, customer experience, and supply chain efficiency. For industries such as food, daily chemicals, electronics, hardware, pharmaceuticals, apparel, and e-commerce, plastic packaging products have become a common packaging solution due to their advantages such as light weight, durability, moisture resistance, strong formability, and controllable costs.
However, in actual procurement, many companies tend to simplify plastic packaging as just “bags, films, boxes, and bottles,” focusing only on unit price while neglecting key factors such as material, thickness, load capacity, sealing performance, printing techniques, environmental requirements, and usage scenarios. This can lead to issues such as packaging damage, product moisture damage, peeling prints, size mismatches, delayed delivery, and even impact sales due to non-compliance with industry standards.
This article will introduce, from a professional packaging industry perspective, the key factors enterprises should focus on when selecting plastic packaging products, helping procurement personnel to more efficiently complete packaging selection and supplier communication.
What are the common plastic packaging products?
There are many types of plastic packaging products, and different industries and products require different packaging forms. Common types include plastic packaging bags, plastic packaging films, plastic packaging boxes, plastic bottles, jars, and containers, as well as custom plastic packaging.
1. Plastic Packaging Bags
PE bags, PP bags, OPP bags, composite bags, self-sealing bags, zipper bags, front-opening bags, carry bags, anti-static bags, vacuum bags, and others are widely used in industries such as food, clothing, electronic components, hardware parts, and daily necessities.
2. Plastic Packaging Film
PE film, POF shrink film, PVC shrink film, stretch film, protective film, composite film, and others are commonly used for product wrapping, transportation protection, pallet securing, surface protection, and combined packaging.
3. Plastic Packaging Box
Blister packs, transparent boxes, folded boxes, trays, and inner trays are suitable for scenarios where products need to be displayed or fixed, such as electronics, food, cosmetics, toys, and medical supplies.
4. Plastic bottles, jars, and buckets packaging
Commonly used for packaging liquid, powder, and granular products, such as personal care items, chemical products, food seasonings, and health supplements.
5. Custom Plastic Packaging
Includes irregular packaging, functional packaging, anti-static packaging, moisture-proof packaging, high barrier packaging, eco-friendly biodegradable packaging, etc., which typically require specialized design based on product characteristics.
Before purchasing, enterprises should first clarify the packaging requirements for the product rather than directly inquiring about the price of a specific material. Choosing the wrong packaging form, even if it is cheaper, may result in higher loss costs.
II. What Key Parameters Should Be Considered When Choosing Plastic Packaging Products?
Plastic packaging may seem simple, but there are many parameters that actually affect its performance. When purchasing, it is recommended to focus on the following key aspects.
Is the material suitable for the product?
Different plastic materials have varying performance characteristics. PE material offers good flexibility and moisture resistance, commonly used for general-purpose packaging bags, inner bags, and stretch films; PP material has high transparency and good rigidity, suitable for display packaging; PET material provides high strength and good transparency, often used for bottles, sheets, and composite packaging; PA, EVOH, and other materials are typically used for high barrier packaging.
If the product requires properties such as moisture resistance, oil resistance, oxidation resistance, heat resistance, transparency, puncture resistance, or food contact safety, you should not only consider price but select the appropriate material based on product characteristics.
2. Does the thickness match the load capacity?
Many packaging issues are not due to poor material quality, but rather improper thickness design. Too thin packaging can lead to bag rupture, punctures, and deformation, while excessive thickness results in unnecessary cost waste.
When purchasing packaging materials, the thickness should be determined based on the product’s weight, shape, sharpness of edges, transportation method, and stacking method. For example, the requirements for packaging strength vary for items such as hardware components, electronic parts, frozen food, and e-commerce express products. If necessary, sample testing, drop testing, or transportation simulation tests should be conducted.
Are the dimensionsReserved reasonable?
Small packaging dimensions can lead to difficulties in bagging, poor sealing, or product deformation. Oversized packaging may affect aesthetics, increase material costs, and also cause movement during transportation.
The appropriate packaging dimensions should be determined based on the product’s length, width, and height, packaging method, sealing method, display requirements, and machine packaging conditions. For automated packaging lines, special attention should be given to the width of the roll film, bag length, heat-seal edge position, and equipment compatibility.
4. Is the sealability and barrier property up to standard?
For industries such as food, pharmaceuticals, precision electronics, and chemical products, the sealing performance of packaging is crucial. Poor sealing, mismatched heat sealing temperatures, and insufficient barrier properties of materials can lead to moisture ingress, oxidation, leakage, or spoilage of the product.
These products should focus on heat-seal strength, oxygen barrier performance, moisture resistance, oil resistance, and low-temperature or high-temperature resistance. If necessary, request the supplier to provide test reports or sample test data.
III. Common Pitfalls in Plastic Packaging Procurement
1. Compare only the unit price and ignore the overall cost
Purchasing packaging should not focus solely on the price per bag or per box. Low-cost packaging with high damage rates, unstable printing, and unreliable delivery schedules can increase costs related to returns, replenishment, manual sorting, and customer complaints. The truly reasonable purchasing approach is to compare the overall cost of using the packaging.
Place an order without confirming the sample
Custom plastic packaging involves multiple details such as size, material, thickness, color, printing, sealing, and opening method. Mass production without sample confirmation can lead to discrepancies between the actual product and the expected outcome. Enterprises should aim to confirm samples before placing bulk orders.
3. Ignore print files and color differences
Packaging printing is not simply applying an image. The resolution of the design file, color mode, spot color requirements, printing method, and base color of the material all affect the final result. Especially for brand packaging, it is essential to confirm the source files such as AI, CDR, and PDF, Pantone color numbers, proofing effects, and acceptable color tolerance in advance.
4. No consideration of storage and transportation environment
Some plastic packaging may experience deformation, adhesion, brittleness, or print wear under high temperature, low temperature, humid conditions, or prolonged stacking. Enterprises should select appropriate materials based on storage duration, transportation distance, packaging methods, and the environmental conditions of the target market.
5. Ignoring Compliance Requirements
Packaging for food contact, pharmaceutical use, export, and eco-friendly applications typically involves different standards. Before procurement, it is essential to clarify whether food-grade materials, environmental certifications, RoHS, REACH, FDA, or other testing requirements are needed to avoid compliance issues affecting sales later on.
Four. How does a company plan product packaging?
A mature product packaging solution goes beyond simply “holding the product” and should also consider protection, display, branding, cost, and efficiency.
First, clarify the packaging objective. Is it for transportation protection or for end-display purposes? Is it intended for e-commerce channels or for in-store shelves? Is the focus on a premium image or on cost-effectiveness? Different objectives will determine different packaging structures and processes.
Secondly, analyze the product characteristics. Is the product fragile, moisture-sensitive, light-sensitive, pressure-sensitive, or prone to oxidation? Does it have sharp edges, contain liquid, powder, or emit an odor? These factors will affect the choice of packaging materials and structural design.
Again, brand visual planning is essential. The logo, text, graphics, color scheme, and information layout on the packaging should align with the brand positioning. For business clients, professional and clear packaging not only enhances product recognition but also builds customer trust.
Finally, cost control and production feasibility must be considered. Complex processes can enhance packaging quality but also increase production costs and lead times. Enterprises should select the appropriate packaging grade based on product pricing, order volume, and sales channels.
V. Introduction to Common Plastic Packaging Processes
1. Blow Molding Process
Primarily used for producing PE films, packaging bag base materials, etc., thickness, width, color, and functional additives can be adjusted according to requirements.
2. Bag Making Process
Includes flat bags, front-opening bags, self-sealing bags, zipper bags, three-side sealed bags, middle-sealed bags, and irregularly shaped bags. Different bag types are suitable for various packaging scenarios.
3. Composite Process
Combining different materials to enhance the barrier properties, strength, stiffness, or heat-sealing performance of packaging, commonly used in food, personal care, and high-performance packaging applications.
4. Printing Process
Includes gravure printing, flexographic printing, screen printing, and digital printing. Large-volume orders are typically suitable for traditional printing, while small-volume or multi-version orders can consider digital printing.
5. Vacuum Forming
Heat the sheet material and form it through vacuum molding to create trays, inner trays, transparent boxes, etc., commonly used for product fixation and display.
6. Heat Shrink Packaging
Heat shrink film adheres to the product surface when heated, suitable for combined packaging, dust protection, and enhancing overall display appearance.
When selecting a process, enterprises should make a comprehensive judgment based on order quantity, appearance requirements, functional requirements, and budget.
Six. How to Choose a Reliable Plastic Packaging Supplier?
A reliable packaging supplier not only provides products but also offers packaging solutions. When selecting a supplier, enterprises should focus on the following aspects: whether the supplier has relevant industry experience; whether they can provide material and structural recommendations based on the product; whether they support sample making and customization; whether they have stable production capacity and effective delivery scheduling; whether they can provide test reports or compliance documents; whether their communication is professional and efficient; and whether they can promptly address after-sales issues.
For long-term purchasing enterprises, choosing a stable, professional, and responsive packaging partner is often more important than a one-time low price.
Conclusion
Plastic packaging plays an important role in modern commerce. A suitable packaging solution not only protects products and reduces transportation losses, but also enhances brand image, optimizes customer experience, and helps enterprises present their products more professionally in market competition.
When purchasing plastic packaging, enterprises should consider factors such as material, size, thickness, manufacturing process, compliance, cost, and application scenarios comprehensively, to avoid focusing solely on price while neglecting actual performance.
