Plastic seals are widely used in various industries and are easy to customize. The most widely used is in the logistics industry, but they are also used in food and beverage, medical aviation, and tourism. Each type has different functions and types, so what are they specifically? Let’s explore!
What types of plastic seals are there?
There are generally the following species types:
1. Variable-Length Plastic Seals
hese adjustable seals are highly versatile and can be tightened as needed, making them ideal for securing a variety of items, such as:
Bags and mail sacks
Chemical drums
First aid kits
Fashion items for online returns
Fire extinguishers
Vehicle fuel tanks
Any object requiring tamper-evident access
2.Fixed-length plastic seals
Unlike variable-length seals, fixed-length seals provide a more tamper-resistant solution due to their rigid structure. They feature a simple ‘click’ locking mechanism, ensuring ease of application. These seals are commonly used in transportation as single-use security solutions for cargo doors, truck latches, and transit containers.
3. Pull-up security seals
Also known as pull-through seals, these disposable security seals tighten as they are applied, restricting unauthorized access to secured items. They are often used in situations where a high-security alternative is required, such as sealing storage units, postal deliveries, and high-value shipments.
4.Plastic seals with wire
A combination of plastic and metal wire, these seals come in adjustable and fixed-length variations. Their reinforced design enhances security, making them suitable for:
Securing industrial equipment
Sealing high-risk shipments
Locking sensitive storage areas
5. Padlock plastic seals
Designed to resemble traditional padlocks, these seals offer defined-length security and are widely used in the aviation industry. Their primary application includes securing airline food trolleys and duty-free carts, ensuring that goods remain protected from tampering during transit.
6. Plastic meter seals
Meter seals are used in utility industries to secure electricity, water, and gas meters. These seals help prevent tampering with essential infrastructure. Anchor seals and twister seals are among the most commonly used varieties, with additional options available for locking safety-critical valves and connectors.
Which type is the most common in logistics?
In the logistics industry, the most commonly used type of plastic seal is the Variable-Length Plastic Seals. These seals are preferred because of their versatility, ease of use, and cost-effectiveness.
Why Are Variable-Length Plastic Seals the Most Common in Logistics?
Because of its adjustable fit and fixed length seal, the Differentiated Tension Seal can be adjusted to suit a variety of applications from truck doors to mail bags, and with your tamper-evident design, the custom fit further enhances the security of your cargo.
How to customize the type of plastic seals?
Businesses can personalize seals based on their specific needs, such as security level, industry application, and tracking requirements. Below are the key customization options:
You need to determine the level of security you need
- Consider your application, such as fixed length seals for truck and container doors, padlockable plastic seals for lockers, duty free shopping carts, etc.
- Consider environmental conditions, that is, the temperature your goods are exposed to
- Determine the additional features you need, such as QR codes, unique serial numbers, tamper evidence, etc.
Based on the above four key points, I think you can choose the type you want.
What is the relationship between the code and the type of plastic seals?
Different plastic seal types may follow specific coding conventions based on length, material, strength, and application:
| Seal Type | Code Relationship | Common Features |
|---|---|---|
| Variable-Length Seals | Codes may indicate length, tensile strength, and color. | Adjustable fit, used for securing bags, containers, etc. |
| Fixed-Length Seals | Codes typically specify standard length and lock strength. | Provides consistent security; ideal for logistics and transport. |
| Wire Plastic Seals | Codes indicate wire material (metal), thickness, and length. | Used for high-security applications like meters and industrial equipment. |
| Padlock Plastic Seals | Codes may specify locking mechanism and seal length. | Small, easy-to-apply locks, often used in retail and aviation. |
| Plastic Meter Seals | Codes indicate meter type compatibility (electric, gas, water). | Specifically designed to secure utility meters, preventing unauthorized access. |
What is the safest type of plastic seals?
The safest type of plastic seals generally depend on the security level required for the specific application. However, in general, wire plastic seals are often considered the safest options for high-security applications.
Wire Plastic Seals are often considered the most secure because they have metal reinforcement (usually steel wire) that is difficult to break or tamper with.
