Paper Sticker Problems

01

Easy Counterfeiting and Tampering

The label can be removed and replaced easily, especially in cases of pesticide counterfeiting.

02

Damage from Moisture, Solvents and Sunlight

The label is affected by moisture, solvents and sunlight.

03

Adhesive Failure and Label Falling

Adhesive may dry during storage and transportation, causing the label to detach.

04

Air Bubbles

Air bubbles may appear because of an uneven surface or incorrect application speed.

02

Printing Problems

01

Ink Damage from Solvents

Pesticide solvents can attack the ink and cause printed information to disappear.

02

Poor Ink Adhesion

The low surface energy of HDPE containers may cause poor ink adhesion without suitable surface treatment.

03

UV Fading

Exposure to sunlight can fade colors and make warnings less visible.

04

Wear of Printing and Data

Friction during transportation and handling may scratch the print and reduce data readability.

In-Mold Labeling

IML

IML (In-Mold Labeling)

A labeling technology in which the label is placed inside the mold during the manufacturing process, allowing it to bond permanently with the product and become an integral part of the package.

IML Advantages

Why IML?

01

Difficult to Counterfeit

The label is integrated with the package and is difficult to remove or replace.

02

Solvent and Chemical Resistance

Maintains data and colors when exposed to pesticides.

03

Moisture and Sunlight Resistance

Maintains label stability and color quality during storage and use.

04

No Adhesive

Eliminates adhesive drying, failure and label falling problems.

05

Consistent Appearance on Round Packages

Reduces bubbles, wrinkles and edge peeling.

06

Stable Package Printing

Supports Barcode, QR Code and DataMatrix printing suitable for machine reading.

07

Transportation and Storage Durability

Maintains package appearance and information during handling and storage.

08

High Code Accuracy

Maintains data and warnings during transportation and handling.

09

Excellent Stability on Round Packages

Prevents wrinkles, bubbles and edge peeling.

10

High Print Quality

Supports graphics, images, fine details, Barcode and QR Code.
